User Story:
As an OpenShift Engineer I want [opct] create a template of expected user documentation required by partner so partners have a clear path of minimum expected information of this installation document. See existing documents: Installation <https://redhat-openshift-ecosystem.github.io/opct/guides/cluster-validation/installation-review/|Review> and <https://redhat-openshift-ecosystem.github.io/opct/guides/cluster-validation/installation-checklist/|Checklist>. Old partners documentation (G42, <https://docs.oracle.com/pt-br/iaas/Content/openshift-on-oci/overview.htm|Oracle>, etc).

Description:
< Record any background information >

Acceptance Criteria:
< Record how we'll know we're done >

Other Information:
< Record anything else that may be helpful to someone else picking up the card >
