"APIcast with AMP on OpenShift differs from APIcast with AMP hosted and requires unique configuration procedures."
However, this information (e.g. "AMP hosted") could be a bit confusing to some customers.
A suggested draft from Daria Mayorova could be used as a basis to make it more clear:
"When using APIcast with API Manager deployed as part of the full 3scale API Management on-premises installation in OpenShift Container Platform, the configuration procedures will be different from when APIcast is used with API Manager in 3scale SaaS."
