+# 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 successfuly 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.bash
+
+## Sample Usage
+
+To simply run the image:
+
+```
+podman run quay.io/podman/hello
+
+! ... Hello Podman World ...!
+
+         .--"--.

+a local directory and issue these commands:
+
+```
+chmod 755 ./podman_hello_world.bash
+podman build -t myhello .
+podman run myhello
+```
