@Gargron @staticsafe Read the docs is mostly rst with some custom tags. That thing that's good about rst that it's formally defined, unlike having every imaginable markdown flavor under the sun, but the learning curve is a bit steep.
This is a good intro -- https://thomas-cokelaer.info/tutorials/sphinx/rest_syntax.html
I also like OmniMarkupPrviewer when editing rst docs -- https://github.com/timonwong/OmniMarkupPreviewer
This is a very good tutorial, but it's almos 3hrs long :( -- https://www.youtube.com/watch?v=hM4I58TA72g
