Documentation about Trix's format?

[mscheper]

Is there documentation somewhere for how Trix formats text, i.e. which HTML tags it uses?

There are plenty of GitHub issues that make it clear that it doesn't use <p> for paragraphs, and as frustrating as that may be, converting markup for use with Trix would be trivial if there was a comprehensive list of tags it actually does support.

I've done some searching on GitHub and Google and not found such a document, though. Have I missed it?
