Change the docs markdown so that flag names will be h4 headers.
Sphinx will automatically add anchors to headers. Add css to
make sure the flag names are not to big compared to the text.
The man pages also still renders fine but it looks a bit different.

There are many use cases where you want to just mount an image
without creating a container on it. For example you might want
to just examine the content in an image after you pull it for
security analysys. Or you might want to just use the executables
on the image without running it in a container.
The image is mounted readonly since we do not want people changing
images.
