Convenient documentation for those who want to learn FRP

Good day, gentlemen. I am working on documentation for RxJs. For this I use Gitbook, jsbin (for interactive users). It takes quite a lot of time, and if someone has a desire to help, or to offer some interesting improvisation, I will be very happy. There are plans to make more interactive drawing of data that will be emitted via streams. I also plan to translate all this into future in Russian and make a multilingual version.
