That's awesome. This was several months ago when there was a link to some specific Arch Linux documentation that @dansup@mastodon.social mentioned was the most complete. Sounds like it's been cleaned up.
mm. Might have been a getting started from the ground up kind of setup guide and the author might be most familiar with that. But happily it seems like there's docker files in the main repo, including docker compose files, so that should make it quite easy to set up.
