I'm not going to put the effort into making documentation for a language that will never finish development and is very unoptimized. I also don't have the time, especially since I am constantly fixing the bugs people are finding. This project was supposed to be done when the video was released, but because it went viral recently I need to keep it maintained.

If you look at the GitHub readme, there is a new link which points to the site of a user who made some docs.
