[Help] What's the best way to learn this api?

I have been trying to study this api but there is so few examples and I really want to implement this into my website but of anyone could offer to be a contact for help, link me articles and examples, that would be much appreciated

I got the file code from Matthew in this other post I made where he linked http://twitch.apiexampl.es/
