Dear team,
I would like to suggest the following improvements to the docs:

1. In paragraph 'Prerequisites' first bullet point: Add a link to [Red Hat Container Registry Authentication](https://access.redhat.com/articles/RegistryAuthentication) to make it easier for customers to find information on how to access the registry.

2. In paragraph 'Procedure' the first two code blocks suggest to run the commands as an unprivileged user ('$'). By doing so the third step which is performed as root ('#') will fail. All three steps need to be performed as root ('#').

Best regards,
Joerg
