1. Proposed title of this feature request
-->   Improving documentation about installing Openshift baremetal

2. What is the nature and description of the request?
--> From the customer's perspective, documentation about installing an Openshift cluster in a baremetal environment is excessively confusing. Information is spread along different sections whose content sometimes differs from each other.

3. Why does the customer need this? (List the business requirements here)
--> To speed up the installation of Openshift clusters by understanding clearly the requirements needed for each installation method without jumping among different sections of the documentation. 

The current documentation mixes concepts that belong to different installation methods and this creates doubts when planning the deployments of new clusters.

4. List any affected packages or components.
