The Mock tool is an important piece in Fedora packaging,
however its use is not covered well in the Package Maintainer Docs.

In most places, there is probably no need to dive deep into Mock,
because fedpkg mockbuild wraps its
and the discussion should focus on that.
However, it seems plausible that there are some situations
where a Fedora package could want to call Mock directly.
Documentation for those cases, if they exist, should be available here.

The current situation of the documentation:

• There is the wiki page Using Mock to test package builds
• Package Maintainer Docs link to that page from multiple pages
• Mock has its own documentation page,
  which is maintained
• In opinion of the Mock maintainer, the Fedora wiki page should be deleted,
  apart from certain content that would be better move to mock's own docs.

Based on this, a good approach could be to start from cleaning up the wiki page,
moving as much content to the Mock's own documentation
and possible remaining Fedora specifics to Package Maintainer Docs.
