-# Podman Hello World image
-
-## Overview
-
-This directory contains the Containerfile and bash script necessary to create the
-"hello" podman image housed on quay.io under the Podman account in a public
-repository.  The image is public and can be pulled without credentials.
-
-Using this image is helpful to:
-
- * Prove that basic Podman operations are working on the host.
- * Shows that the image was pulled from the quay.io container registry.
- * Container creation was successfully accomplished. (`podman ps -a`)
- * The created container was able to stream output to your terminal.
-
-## Directory Contents
-
-The contents of this directory contain:
- * ./Containerfile
- * ./podman_hello_world.c
-
-## Sample Usage
-
-To simply run the image:
-
-```
-podman run quay.io/podman/hello
-
-!... Hello Podman World ...!
-
-         .--"--.
-       / -     - \
-      / (O)   (O) \
-   ~~~| -=(,Y,)=- |
-    .---. /`  \   |~~
- ~/  o  o \~~~~.----. ~~
-  | =(X)= |~  / (O (O) \
-   ~~~~~~~  ~| =(Y_)=-  |
-  ~~~~    ~~~|   U      |~~

-```
-To build the image yourself, copy the files from this directory into
-a local directory and issue these commands:
-
-```
-podman build -t myhello .
-podman run myhello
-```
-
-## Potential Issues:
-
-The image runs as a rootless user with the UID set to `1000`.
-If the /etc/subuid and /etch/subgid values are not set appropriately to run as a
-rootless user on the host, an error like this might be raised:
-
-```
-Copying blob acab339ca1e8 done
-ERRO[0002] Error while applying layer: ApplyLayer exit status 1 stdout:  stderr: potentially insufficient UIDs or GIDs available in user namespace (requested 0:12 for /var/spool/mail): Check /etc/subuid and /etc/subgid: lchown /var/spool/mail: invalid argument
-Error: writing blob: adding layer with blob "sha256:ee0cde9de8a68f171a8c03b0e9954abf18576947e2f3187e84d8c31ccd8f6a09": ApplyLayer exit status 1 stdout:  stderr: potentially insufficient UIDs or GIDs available in user namespace (requested 0:12 for /var/spool/mail): Check /etc/subuid and /etc/subgid: lchown /var/spool/mail: invalid argument

-## THANKS!
-
-Many Thanks to @afbjorklund for a great discussion during the
-first revision of this container image that resulted in moving
-from using bash to using C, and the ensuing changes to the
-Containerfile.
-
-Also many thanks to @mairin for the awesome ASCII art!
