Section Number and Name: 
Chapter 5. Using Cluster Loader

Describe the issue: 
In the procedure there is registry.svc.ci.openshift.org, however that's Upstream and to use it there is need for a token available only for openshift org members on GitHub

Suggestions for improvement: 
either:
1. we need to mirror it to our repos and put in the guide a different URL
or
2. we describe method how to get a token and login to registry.svc.ci.openshift.org
3. maybe there is a different method to podman login registry.svc.ci.openshift.org that I am not aware
