Review few docs for upcoming 2.1.0 release

[Nikita Beloglazov]

Hi

I'm preparing 2.1.0 release and have written a couple of docs for it. I would be happy if someone agreed to review it as I expect grammatical and other kind of errors there. Ideally it would be native English speaking person or someone who feels confident in English grammar.

Is anyone interested?

Thanks,

Nikita
