Docs: add tutorial for setup

Hi @acgruber,

I would appreciate some feedback if this is what we are aiming at from the perspective of style and information density. I will try to find someone that looks into this from the perspective of the content.

Kind regards!

Hi @klees,

This is exactly what we're aiming for both in terms of style and density. Great example of how to use enganging language to guide a newbie through an article as well. Thanks a lot for this contribution!

Cheers!
