While T74794 https://phabricator.wikimedia.org/T74794 develops and is fixed, I've published the frontend docs on my site to help with some refactorings:

If at some point somebody needs it updated, feel free to pull request or ping me and I'll gladly update them. Hopefully it wont take long and I'll remove this soon.
Cheers!
