Move documentation to GitHub Wiki

[stefan-niedermann]

Please move the documentation to GitHub Wiki. I had to read many long issues until i found it 😉

[Henni]

I didn't know this existed ;)
Is this still up to date @v1r0x ?

[v1r0x]

Never heard of this. Looks like nothing/most of it isn't implemented.

I think I messed up. Thought I could add separate wikis for different branches so I made wiki branch and converted that to google doc to markdown just in case you guys end up needing it.

Now it looks like it added it for the master branch also and I can't delete it since I'm not repo owner :(

So sorry, I'll make this up someday with bugfixes

Found it in #1 - maybe it should be adjusted and a comment left there. If anyone wants to collaborate, one will not find API-information (or old information).

Ideally there is a entry in the README.md
