I’ve created a branch in the Twitch-API repo to create chat system documentation: https://github.com/justintv/Twitch-API/tree/chat_docs/chat
This has been on my personal TODO list for a while and unfortunately its still not a reality. As an interim solution, I decided to at least create the branch and make you aware in case any of you had interest sending a pull request to document the chat system. I’ve created a basic taxonomy as a guideline, but feel free to suggest changes.
Thanks!
