Use of MultiCloudGateway depreciated and makes no sense in guide    

    Every reading of the docs

Head to https://docs.openshift.com/container-platform/4.15/migration_toolkit_for_containers/installing-mtc.html#configuring-replication-repository_installing-mtc - the paragraph says:

"You must retrieve the Multicloud Object Gateway (MCG) credentials and S3
 endpoint in order to configure MCG as a replication repository for the 
Migration Toolkit for Containers (MTC).
You must retrieve the Multicloud Object Gateway (MCG) credentials in 
order to create a Secret custom resource (CR) for the OpenShift API for Data Protection (OADP)." which is not only a mouth-ful but with https://catalog.redhat.com/software/containers/ocs4/mcg-core-rhel8/5ddef5fb5a13461646f7f45e?architecture=amd64&image=64243f99cd0eb61355af9adf stating MCG is depreacted and replaced/implemented by Noobaa the sentence is everything but helpful.

Several aspects needs addressing. An abstract description of the need that isn't dependent of the storage platform used (from there links to specific implementations on AWS, ODF etc would be great).  Phrasing and linking from overall statements to details like "what secret" and how to extract tokens for logins and a lot more. As is, the guide isn't helping with the proper configuration, let alone explaining what security features are required for the login the cluster definition requires, and the S3 ditto.

    Workable documentation
