+## Subscriptions
+
+When executing `image-builder-cli` via `podman`, subscription information is
+passed to the container and used to access Red Hat CDN. As long as the host
+machine is properly subscribed with attached Red Hat Enterprise Linux
+subscription, building RHEL images will work automatically.

+To use content from Red Hat Satellite, follow the extra repositories section
