@philvarner Thanks for all of the hard work on this project.

Figured I could contribute in some small way and fixed the docs that have been out of date for over a year. I built them to mirror the /api.html endpoint exactly. All of this was automated using GitHub Actions and Pages. It's a separate action per GitHub's recommendation.
