-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<https://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<https://www.gnu.org/licenses/why-not-lgpl.html>.

+
+## Installation
+
+<!-- start install -->
+
+While installing Manim Slides and its dependencies on your global Python is fine, I recommend using a virtual environment (e.g., [venv](https://docs.python.org/3/tutorial/venv.html)) for a local installation.
+
+### Dependencies
+
+<!-- start deps -->
+
+Manim Slides requires either Manim or ManimGL to be installed. Having both packages installed is fine too.
+
+If none of those packages are installed, please refer to their specific installation guidelines:
+- [Manim](https://docs.manim.community/en/stable/installation.html)
+- [ManimGL](https://3b1b.github.io/manim/getting_started/installation.html)
+
+<!-- end deps -->
+
+### Pip Install
+
+The recommended way to install the latest release is to use pip:
+
+```bash
+pip install manim-slides
 ```
-pip install manim_presentation opencv-python
+
+Optionally, you can also install Manim or ManimGL using extras[^1]:
+
+```bash
+pip install manim-slides[manim]   # For Manim
+# or
+pip install manim-slides[manimgl] # For ManimGL
 ```
 
+[^1]: NOTE: you still need to have Manim or ManimGL platform-specific dependencies installed on your computer.
+
+### Install From Repository
+
+An alternative way to install Manim Slides is to clone the git repository, and install from there: read the [contributing guide](https://eertmans.be/manim-slides/contributing/workflow.html) to know how.
+
+<!-- end install -->
+
 ## Usage
 
-Use the class `Slide` as your scenes base class
+<!-- start usage -->
+
+Using Manim Slides is a two-step process:
+1. Render animations using `Slide` (resp. `ThreeDSlide`) as a base class instead of `Scene` (resp. `ThreeDScene`), and add calls to `self.next_slide()` everytime you want to create a new slide.
+2. Run `manim-slides` on rendered animations and display them like a *Power Point* presentation.
+
+The documentation is available [online](https://eertmans.be/manim-slides/).
+
+### Basic Example
+
+Wrap a series of animations between `self.start_loop()` and `self.stop_loop()` when you want to loop them (until input to continue):
 
 ```python
-from manim_presentation import Slide
+# example.py
 
-class Example(Slide):
-    def construct(self):
-        ...
-```
-
-call `self.pause()` when you want to pause the playback and wait for an input to continue (check the keybindings)
-
-Wrap a series of animations between `self.start_loop()` and `self.stop_loop()` when you want to loop them (until input to continue)
-
-```python
 from manim import *
-from manim_presentation import Slide
+# or: from manimlib import *
+from manim_slides import Slide
 
-class Example(Slide):
+class BasicExample(Slide):
     def construct(self):
         circle = Circle(radius=3, color=BLUE)
         dot = Dot()
 
         self.play(GrowFromCenter(circle))
-        self.pause()
+        self.next_slide()  # Waits user to press continue to go to the next slide
 
-        self.start_loop()
+        self.start_loop()  # Start loop
         self.play(MoveAlongPath(dot, circle), run_time=2, rate_func=linear)
-        self.end_loop()
+        self.end_loop()  # This will loop until user inputs a key
 
         self.play(dot.animate.move_to(ORIGIN))
-        self.pause()
+        self.next_slide()  # Waits user to press continue to go to the next slide
+```
 
-        self.wait()
+First, render the animation files:
+
+```bash
+manim example.py BasicExample
+# or
+manimgl example.py BasicExample
 ```
 
 To start the presentation using `Scene1`, `Scene2` and so on simply run:
 
-```
-manim_presentation Scene1 Scene2...
+```bash
+manim-slides [OPTIONS] Scene1 Scene2...
 ```
 
-## Default Keybindings
+Or in this example:
 
-Default keybindings to control the presentation
-
-|  Keybinding |          Action          |
-|:-----------:|:------------------------:|
-| Right Arrow |    Continue/Next Slide   |
-|  Left Arrow |      Previous Slide      |
-|      R      | Re-Animate Current Slide |
-|   Spacebar  |        Play/Pause        |
-|      Q      |           Quit           |
-
-## Run Example
-
-Clone this repository
-
-```
-git clone https://github.com/galatolofederico/manim-presentation.git
-cd manim-presentation
+```bash
+manim-slides BasicExample
 ```
 
-Create a virtualenv
+<!-- end usage -->
 
-```
-virtualenv --python=python3.7 env
-. ./env/bin/activate
+##  Key Bindings
+
+The default key bindings to control the presentation are:
+
+<picture>
+  <source media="(prefers-color-scheme: dark)" srcset="https://raw.githubusercontent.com/jeertmans/manim-slides/main/static/wizard_dark.png">
+  <source media="(prefers-color-scheme: light)" srcset="https://raw.githubusercontent.com/jeertmans/manim-slides/main/static/wizard_light.png">
+  <img alt="Manim Slides Wizard" src="https://raw.githubusercontent.com/jeertmans/manim-slides/main/static/wizard_light.png">
+</picture>
+
+
+You can run the **configuration wizard** to change those key bindings:
+
+```bash
+manim-slides wizard
 ```
 
-Install `manim` and `manim_presentation`
+A default file can be created with:
 
-```
-pip install manim manim_presentation opencv-python
+```bash
+manim-slides init
 ```
 
-Render the example scene
+> **_NOTE:_**  `manim-slides` uses key codes, which are platform dependent. Using the configuration wizard is therefore highly recommended.
 
-```
-manim -qh example.py

+## F.A.Q
+
+### How to increase quality on Windows
+
+On Windows platform, one may encounter a lower image resolution than expected. Usually, this is observed because Windows rescales every application to fit the screen.
+As found by [@arashash](https://github.com/arashash), in [#20](https://github.com/jeertmans/manim-slides/issues/20), the problem can be addressed by changing the scaling factor to 100%:
+
+![Windows Fix Scaling](static/windows_quality_fix.png)

+# Contributing
+
+Thank you for your interest in Manim Slides! ✨
+
+Manim Slides is an open source project, first created as a fork of
+[manim-presentation](https://github.com/galatolofederico/manim-presentation)
+(now deprecated in favor to Manim Slides),
+and we welcome contributions of all forms.
+
+This section is here to help fist-time contributors know how they can help this
+project grow. Whether you are already familiar with Manim or GitHub,
+it is worth taking a few minutes to read those documents!

+# Internals
+
+Manim-Slides' work in split in two steps: first, when rendering animation, and, second, when converting multiple animations into one slides presentation.
+
+## Rendering
+
+To render animations, Manim Slides simply uses Manim or ManimGL, and creates some additional output files that it needs for the presentation.
+
+## Slides presentation
+
+Manim Slides searches for the local artifacts it generated previously, and concatenates them into one presentation. For the graphical interface, it uses `PySide6`.

+# Workflow
+
+This document is there to help you recreate a working environment for Manim Slides.
+
+## Dependencies
+
+```{include} ../../../README.md
+:start-after: <!-- start deps -->
+:end-before: <!-- end deps -->
+```
+
+## Forking the repository and cloning it locally
+
+We use GitHub to host Manim Slides' repository, and we encourage contributors to use git.
+
+Useful links:
+
+* [GitHub's Hello World](https://docs.github.com/en/get-started/quickstart/hello-world).
+* [GitHub Pull Request in 100 Seconds](https://www.youtube.com/watch?v=8lGpZkjnkt4&ab_channel=Fireship).
+
+Once you feel comfortable with git and GitHub, [fork](https://github.com/jeertmans/manim-slides/fork) the repository, and clone it locally.
+
+As for every Python project, using virtual environment is recommended to avoid conflicts between modules. For Manim Slides, we use [Poetry](https://python-poetry.org/docs/#installing-with-the-official-installer). If not already, please install it.
+
+## Installing Python modules
+
+With Poetry, installation becomes straightforward:
+
+```bash
+poetry install
+```
+
+This, however, only installs the minimal set of dependencies to run the package.
+
+If you would like to install Manim or ManimGL, as documented in the [quickstart](../quickstart),
+you can use the `--extras` option:
+
+```bash
+poetry install --extras manim   # For Manim
+# or
+poetry install --extras manimgl # For ManimGL
+```
+
+Additionnally, Manim Slides comes with group dependencies for development purposes:
+
+```bash
+poetry install --with dev  # For linters and formatters
+# or
+poetry install --with docs # To build the documentation locally
+```
+
+Another group is `test`, but it is only used for
+[GitHub actions](https://github.com/jeertmans/manim-slides/blob/main/.github/workflows/test_examples.yml).
+
+:::{note}
+You can combine any number of groups or extras when installing the package locally.
+:::
+
+## Running commands
+
+As modules were installed in a new Python environment, you cannot use them directly in the shell.
+Instead, you either need to prepend `poetry run` to any command, e.g.:
+
+```bash
+poetry run manim-slides wizard
+```
+
+or enter a new shell that uses this new Python environment:
+
+```
+poetry shell
+manim-slides wizard
+```
+
+## Testing your code
+
+Most of the tests are done with GitHub actions, thus not on your computer. The only command you should run locally is `pre-commit run --all-files`: this runs a few linter and formatter to make sure the code quality and style stay constant across time. If a warning or an error is displayed, please fix it before going to next step.
+
+## Proposing changes
+
+Once you feel ready and think your contribution is ready to be reviewed, create a [pull request](https://github.com/jeertmans/manim-slides/pulls) and wait for a reviewer to check your work!
+
+Many thanks to you!

+
+Thefore, we only document here the methods we think the end-user will ever use, not the methods used internally when rendering.

+```
+
+or
+
+```python
+from manimlib import *

+
+## Subclass Custom Scenes
+
+For compatibility reasons, Manim Slides only provides subclasses for
+`Scene` and `ThreeDScene`.
+However, subclassing other scene classes is totally possible,
+and very simple to do actually!
+
+[For example](https://github.com/jeertmans/manim-slides/discussions/185),
+you can subclass the `MovingCameraScene` class from `manim`
+with the following code:
+
+```{code-block} python
+:linenos:
+
+from manim import *
+from manim_slides import Slide
+
+
+class MovingCameraSlide(Slide, MovingCameraScene):
+    pass
+```
+
+And later use this class anywhere in your code:
+
+
+```{code-block} python
+:linenos:
+
+class SubclassExample(MovingCameraSlide):
+    def construct(self):
+        eq1 = MathTex("x", "=", "1")
+        eq2 = MathTex("x", "=", "2")
+
+        self.play(Write(eq1))
+
+        self.next_slide()
+
+        self.play(
+            TransformMatchingTex(eq1, eq2),
+            self.camera.frame.animate.scale(0.5)
+        )
+
+        self.wait()
+```
+
+:::{note}
+If you do not plan to reuse `MovingCameraSlide` more than once, then you can
+directly write the `construct` method in the body of `MovingCameraSlide`.
+:::
+
+## Advanced Example

+A more advanced example is `ConvertExample`, which is used as demo slide and tutorial.

+# Graphical User Interface
+
+Manim Slides' graphical user interface (GUI) is the *de facto* way to present slides.
+
+If you do not specify one of the commands listed in the [CLI reference](./cli),
+Manim Slides will use **present** by default, which launches a GUI window,
+playing your scene(s) like so:
+
+```bash
+manim-slides [present] [SCENES]...
+```
+
+Some optional parameters can be specified and can be listed with:
+
+```bash
+manim-slides present --help
+```
+
+:::{note}
+All the `SCENES` must be in the same folder (`--folder DIRECTORY`), which
+defaults to `./slides`. If you rendered your animations without changing
+directory, you should not worry about that :-)
+:::
+
+## Configuration File
+
+It is possible to configure Manim Slides via a configuration file, even though
+this feature is currently limited. You may initiliaze the default configuration
+file with:
+
+```bash
+manim-slides init
+```
+
+:::{warning}
+Note that, by default, Manim Slides will use default key bindings that are
+platform-dependent. If you decide to overwrite those with a config file, you may
+encounter some problems from platform to platform.
+:::
+
+## Configuring Key Bindings
+
+If you wish to use other key bindings than the defaults, you can run the
+configuration wizard with:
+
+```bash
+manim-slides wizard
+```
+
+A similar window to the image below will pop up and prompt to change keys.
+
+```{eval-rst}
+.. image:: ../_static/wizard_light.png

+multiple key binding for the same action by modifying the config file.

+# HTML Presentations
+
+Manim Slides allows you to convert presentations into one HTML file, with
+[RevealJS](https://revealjs.com/). This file can then be opened with any modern
+web browser, allowing for a nice portability of your presentations.
+
+As with every command with Manim Slides, converting slides' fragments into one
+HTML file (and its assets) can be done in one command:
+
+```bash
+manim-slides convert [SCENES]... DEST
+```
+
+where `DEST` is the `.html` destination file.
+
+## Configuring the Template
+
+Many configuration options are available through the `-c<option>=<value>` syntax.
+Most, if not all, RevealJS options should be available by default. If that is
+not the case, please
+[fill an issue](https://github.com/jeertmans/manim-slides/issues/new/choose)
+on GitHub.
+
+You can print the list of available options with:
+
+```bash
+manim-slides convert --show-config
+```
+
+## Using a Custom Template
+
+The default template used for HTML conversion can be found on
+[GitHub](https://github.com/jeertmans/manim-slides/blob/main/manim_slides/data/revealjs_template.html)
+or printed with the `--show-template` option.
+If you wish to use another template, you can do so with the
+`--use-template FILE` option.

+# Sharing your slides
+
+Maybe one of the most important features is the ability to share your
+presentation with other people, or even with yourself but on another computer!
+
+There exists a variety of solutions, and all of them are exposed here.
+
+We will go from the *most restrictive* method, to the least restrictive one.
+If you need to present on a computer without prior knowledge on what will be
+installed on it, please directly refer to the last sections.
+
+> **NOTES:** in the next sections, we will assume your animations are described
+in `example.py`, and you have one presentation called `BasicExample`.
+
+## With Manim Slides installed on the target machine
+
+If Manim Slides, Manim (or ManimGL), and their dependencies are installed, then
+using `manim-slides present` allows for the best presentations, with the most
+options available.
+
+### Sharing your Python file(s)
+
+The lightest way to share your presentation is with the Python files that
+describe the slides.
+
+If you have such files, you can recompile the animations locally, and use
+`manim-slides present` for your presentation. You may want to copy / paste
+you own `.manim-slides.json` config file, but it is **not recommended** if
+you are sharing from one platform (e.g., Linux) to another (e.g., Windows) as
+the key bindings might not be the same.
+
+Example:
+
+```bash
+# If you use ManimGl, replace `manim` with `manimgl`
+manim example.py BasicExample
+
+# This or `manim-slides BasicExample` works since
+# `present` is implied by default
+manim-slides present BasicExample
+```
+
+### Sharing your animations files
+
+If you do not want to recompile all the animations, you can simply share the
+slides folder (defaults to `./slides`). Then, Manim Slides will be able to read
+the animations from this folder and its subdirectories.
+
+Example:
+
+```bash
+# Make sure that the slides directory is in the current
+# working directory, or specify with `--folder <FOLDER>`
+manim-slides present BasicExample
+```
+
+and the corresponding tree:
+
+```
+.
+└── slides
+    ├── BasicExample.json
+    └── files
+        └── BasicExample (files not shown)
+```
+
+## Without Manim Slides installed on the target machine
+
+An alternative to `manim-slides present` is `manim-slides convert`.
+Currently, HTML and PPTX conversion are available, but do not hesitate to propose
+other formats by creating a
+[Feature Request](https://github.com/jeertmans/manim-slides/issues/new/choose),
+or directly proposing a
+[Pull Request](https://github.com/jeertmans/manim-slides/compare).
+
+A major advantage of HTML files is that they can be opened cross-platform,
+granted one has a modern web browser (which is pretty standard).
+
+### Sharing HTML and animation files
+
+First, you need to create the HTML file and its assets directory.
+
+Example:
+
+```bash
+manim-slides convert BasicExample basic_example.html
+```
+
+Then, you need to copy the HTML files and its assets directory to target location,
+while keeping the relative path between the HTML and the assets the same. The
+easiest solution is to compress both the file and the directory into one ZIP,
+and to extract it to the desired location.
+
+By default, the assets directory will be named after the main HTML file, using `{basename}_assets`.
+
+Example:
+
+```
+.
+├── basic_example_assets
+│   ├── 1413466013_2261824125_223132457.mp4
+│   ├── 1672018281_2145352439_3942561600.mp4
+│   └── 1672018281_3136302242_2191168284.mp4
+└── basic_example.html
+```
+
+Then, you can simply open the HTML file with any web browser application.
+
+If you want to embed the presentation inside an HTML web page, a possibility is
+to use an `iframe`:
+
+```html
+<div style="position:relative;padding-bottom:56.25%;">
+    <!-- 56.25 comes from aspect ratio of 16:9, change this accordingly -->
+    <iframe
+        style="width:100%;height:100%;position:absolute;left:0px;top:0px;"
+        frameborder="0"
+        width="100%"
+        height="100%"
+        allowfullscreen
+        allow="autoplay"
+        src="basic_example.html">
+    </iframe>
+</div>
+```
+
+The additional code comes from
+[this article](https://faq.dailymotion.com/hc/en-us/articles/360022841393-How-to-preserve-the-player-aspect-ratio-on-a-responsive-page)
+and it there to preserve the original aspect ratio (16:9).
+
+
+### Sharing ONE HTML file
+
+A future feature, that will be available once
+[#122](https://github.com/jeertmans/manim-slides/issues/122) is solved, will be
+to include all animations as data URI encoded, within the HTML file itself.
+
+### Over the internet
+
+Finally, HTML conversion makes it convenient to play your presentation on a
+remote server.
+
+This is how your are able to watch all the examples on this website. If you want
+to know how to share your slide with GitHub pages, see the
+[workflow file](https://github.com/jeertmans/manim-slides/blob/main/.github/workflows/pages.yml).
+
+> **WARNING:** keep in mind that playing large video files over the internet
+can take some time, and *glitches* may occur between slide transitions for this
+reason.
+
+### With PowerPoint (*EXPERIMENTAL*)
+
+A recent conversion feature is to the PowerPoint format, thanks to the
+`python-pptx` package. Even though it is fully working,
+it is still considered in an *EXPERIMENTAL* status because we do not
+exactly know what versions of PowerPoint (or LibreOffice Impress) are supported.
+
+Basically, you can create a PowerPoint in a single command:
+
+```bash
+manim-slides convert --to=pptx BasicExample basic_example.pptx
+```
+
+All the videos and necessary files will be contained inside the `.pptx` file, so
+you can safely share it with anyone. By default, the `poster_frame_image`, i.e.,
+what is displayed by PowerPoint when the video is not playing, is the first
+frame of each slide. This allows for smooth transitions.
+
+In the future, we hope to provide more features to this format,
+so feel free to suggest new features too!
+
+### Static PDF presentation
+
+If you ever need backup slides, that are only made of PDF pages
+with static images, you can generate such a PDF with the following command:
+
+```bash
+manim-slides convert --to=pdf BasicExample basic_example.pdf
+```
+
+Note that you will lose all the benefits from animated slides. Therefore,
+this is only recommended to be used as a backup plan. By default, the last frame
+of each slide will be printed. This can be changed to be the first one with
+`-cframe_index=first`.

+# Summary
+
+Manim Slides is a Python package that makes presenting Manim animations
+straightforward. With minimal changes required to pre-existing code, one can
+slide through animations in a *PowerPoint-like* manner, or share its slides
+*online* using ReavealJS' power.
+
+# Introduction
+
+Presenting educational content has always been a difficult task, especially
+when it uses temporal or iterative concepts. During the last decades, the
+presence of computers in classrooms for educational purposes has increased
+enormously, allowing teachers to show animated or interactive content.
+
+With the democratization of YouTube, many people have decided to use this
+platform to share educational content. Among these people, Grant Sanderson, a
+YouTuber presenting videos on the theme of mathematics, quickly became known
+for his original and quality animations. In 2018, Grant announced in a video
+that he creates his animations using a self-developed Python tool called Manim
+[@manim-announcement]. In 2019, he made the Manim source code public [@manimgl],
+so anyone can use his tool. Very quickly, the community came together and, in
+2020, created a "fork" of the original GitHub repository [@manimce], in order to
+create a more accessible and better documented version of this tool. Since then,
+the two versions are differentiated by using ManimGL for Grant Sanderson's
+version, as it uses OpenGL for rendering, and ManimCE for the community edition
+(CE).
+
+Despite the many advantages of the Manim tool in terms of illustrating
+mathematical concepts, one cannot help but notice that most presentations,
+whether in the classroom or at a conference, are mainly done with PowerPoint
+or PDF slides. One of the many advantages of these formats, as opposed to videos
+created with Manim, is the ability to pause, rewind, etc., whenever you want.
+
+To face this problem, in 2021, the manim-presentation tool was created
+[@manim-presentation]. This tool allows you to present Manim animations as you
+would present slides: with pauses, slide jumps, etc. However, this tool has
+evolved very little since its inception and does not work with ManimGL.
+
+In 2022, Manim Slides has been created from manim-presentation, with the aim
+to make it a more complete tool, better documented, and usable on all platforms
+and with ManimCE or ManimGL. After almost a year of existence, Manim Slides has
+evolved a lot (see
+[comparison section](#comparison-with-manim-presentation)),
+has built a small community of contributors, and continues to
+provide new features on a regular basis.
+
+# Easy to Use Commitment
+
+Manim Slides is commited to be an easy-to-use tool, with minimal installation
+procedure and few modifications required. It can either be used locally with its
+graphical user interface (GUI), or shared via one of the two formats it can
+convert to:
+
+* an HTML page thanks to the RevealJS Javascript package [@revealjs];
+* or a PowerPoint (`.pptx`) file.
+
+This work has a very similar syntax to Manim and offers a comprehensive
+documentation hosted on [GitHub pages](https://jeertmans.github.io/manim-slides/), see
+\autoref{fig:docs}.
+
+![Manim Slides' documentation homepage.\label{fig:docs}](docs.png)
+
+# Example usage
+
+We have used manim-presentation for our presentation at the COST
+Interact, hosted in Lyon, 2022, and
+[available online](https://web.archive.org/web/20230507184944/https://eertmans.be/posts/cost-interact-presentation/).
+This experience highly motivated the development of Manim Slides, and our
+EuCAP 2023 presentation slides are already
+[available online](https://web.archive.org/web/20230507211243/https://eertmans.be/posts/eucap-presentation/), thanks
+to Manim Slides' HTML feature.
+
+Also, one of our users created a short
+[video tutorial](https://www.youtube.com/watch?v=Oc9g89VzKsY&ab_channel=TheoremofBeethoven)
+and posted it on YouTube.
+
+# Stability and releases
+
+Manim Slides is continously tested on most recent Python versions, both ManimCE
+and ManimGL, and on all major platforms: **Ubuntu**, **macOS** and **Windows**. Due to Manim
+Slide's exposed API being very minimal, and the variety of tests that are
+performed, this tool can be considered stable over time.
+
+New releases are very frequent, as they mostly introduce enhancements or small
+documention fixes, and the command-line tool automatically notifies for new
+available updates. Therefore, regularly updating Manim Slides is highly
+recommended.
+
+# Statement of Need
+
+Similar tools to Manim Slides also exist, such as its predecessor,
+manim-presentation [@manim-presentation], or the web-based alternative, Manim
+Editor [@manim-editor], but none of them provide the documentation level nor the
+amount of features that Manim Slides strives to. This work makes the task of
+presenting Manim content in front of an audience much easier than before,
+allowing presenters to focus more on the content of their slides, rather than on
+how to actually present them efficiently.
+
+## Target Audience
+
+Manim Slides was developed with the goal of making educational content more
+accessible than ever. We believe that researchers, professors, teaching
+assistants and anyone else who needs to teach scientific content can benefit
+from using this tool. The ability to pace your presentation yourself is
+essential, and Manim Slides gives you that ability.
+
+## A Need for Portability
+
+One of the major concerns with presenting content in a non-standard format
+(i.e., not just a plain PDF) is the issue of portability.
+Depending on the programs available, the power of the target computer,
+or the access to the internet, not all solutions are equal.
+From the same configuration file, Manim Slides offers a series of solutions to
+share your slides, which we discuss on our
+[Sharing your slides](https://jeertmans.github.io/manim-slides/reference/sharing.html)
+page.
+
+## Comparison with manim-presentation
+
+Starting from [@manim-presentation]'s original work, Manim Slides now provides
+numerous additional features.
+A non-exhaustive list of those new features is as follows:
+
+* ManimGL compatibility;
+* playing slides in reverse;
+* exporting slides to HTML and PowerPoint;
+* 3D scene support;
+* multiple key inputs can map to the same action
+  (e.g., useful when using a pointer);
+* optionally hiding mouse cursor when presenting;
+* recording your presentation;
+* multiple video scaling methods (for speed-vs-quality tradeoff);
+* and automatic detection of some scene parameters
+  (e.g., resolution or background color).
+
+The complete and up-to-date set of features Manim Slide supports is
+available in the
+[online documentation](https://jeertmans.github.io/manim-slides/).
+For new feature requests, we highly encourage users to
+[create an issue](https://github.com/jeertmans/manim-slides/issues/new/choose)
+with the appropriate template.
+
+# Acknowledgements
