I can pick this up if no one's started on it?

@rarmatei Thanks for your support. But we have recently changed the repository to the rxjs repo https://github.com/ReactiveX/rxjs. I would really appreciate a pr on this, but please do it in that repository. If you have any questions on that, don't hesitate to ask me. Thank you

@jwo719 Oh, I see, thanks for pointing that out!

I'm definitely missing something but I can't seem to find where the operator docs are under the repo you linked to?

I'll submit a PR to this repo today if that's okay, since I have some free time - and I can transfer it to the new one later in the week, once you get a chance to point me in the right direction?

EDIT: I got it, they're generated from the actual operator sources. Will submit a PR there 👍
