Hosting Docs #894

I've noticed that besides the ReadMe and one Wiki page (and the video), there's no other documentation available.

For the Core update, we need at least these doc pages:

• What's new
  (already have that)
• Migration Guide
• Getting Started Guide
  to unclutter the readme and explain new ways for settings up

I think none of us has time and interest to set up some hosting just for a few pages.
As it's no the first time, facing that kind of situation, I could offer a simple zero-setup solution for this, if you like: https://github.com/softworkz/ffmpeg_output_apis/wiki/Concept-of-this-Repo

If you do, I could create a PR to enable this..
