Section Number and Name: Preparation & Installation

Describe the issue: There should be a explicit warning/note about mirroring the OLM (https://docs.openshift.com/container-platform/4.5/operators/admin/olm-restricted-networks.html) in a disconnected environment.

Suggestions for improvement: Add a note linking to the olm on restricted network document explicitly.
