Review Request #11778 — Created Aug. 10, 2021 and submitted
This fleshes out the docs, listing the file types that are supported,
adding installation instructions for the tool, adding tips on
configuring a proper build environment for Clang, and covering all
configuration options (both worker-side and in Review Board). This
should help users get set up for the first time.
Built the docs. Checked for build errors, spelling errors, and bad links.
