documentation

[alcohol]

I want to move some of the docs from https://getcomposer.org/doc/articles/handling-private-packages-with-satis.md into the docs directory, and improve them. Currently they are not easy to find, not very precise/detailed and overal just not great (in my opinion).

Any help, thoughts and feedback is appreciated.

That's a good idea. I can write a short tutorial if you want.

Yeah I made a start, you can see results so far at https://composer.github.io/satis/ (this is based on contents of /docs/ folder). Feel free to submit a PR against said directory.
