The "Before You Begin" chapter of xPaaS docs should just refer to OpenShift docs on how to get access to OpenShift (oc cluster, etc) or install one instead of repeating a brief set of bullet points on how to install it: https://access.redhat.com/documentation/en/red-hat-xpaas/0/paged/red-hat-xpaas-fuse-integration-services-image/chapter-2-before-you-begin
This is now updated. https://access.redhat.com/documentation/en-us/red_hat_jboss_middleware_for_openshift/3/html/red_hat_jboss_fuse_integration_services_for_openshift/before_you_begin Moving this to CLOSED-->CURRENTRELEASE.
