@maxachis yeah, I don't know how to test complicated markup like this either...I gave you creator permissions in gitbook, so you don't have to wait for an approval to update the docs. do you want to try doing it there? for less structural edits, it's still possible to just do them in github like this.

I would ask that you just link to one PR from the other, but you already have a habit of doing that, so thank you for that!

Closed in favor of the Gitbook doc pull request.
