The documentation only explains which resources should be created (BareMetalHosts, OpenStackDataPlaneNodeSet, OpenStackDataPlaneDeployment). It is hard to understand the installation flow of a dataplane deployment with unprovisioned nodes: https://docs.redhat.com/en/documentation/red_hat_openstack_services_on_openshift/18.0/html/deploying_red_hat_openstack_services_on_openshift/assembly_creating-the-data-plane#assembly_creating-a-data-plane-with-unprovisioned-nodes_dataplane

It will be good to have:

• which components are responsible for these resources,
• what is expected to happen during each step,
• how each step can be troubleshooted

Having this information is critical in case things don't just follow the "happy path".
