Description of the problem:

The instructions should include the expectation that RHDH is already deployed with a running Backstage instance. The expectation should be that the Backstage instance already has certain minimum prerequisites set up. 

In addition, the following links in the "Installing the Orchestrator on existing RHDH instance" docs are incorrect, and link to the wrong line:

• "To ensure you are utilizing the latest versions, please consult the Helm chart values available here"
• "Register new templates into the catalog from the specified source"

How reproducible: 100%

Expected results: 
Links should link to the correct sources.
