Important for you maybe. It's not terribly so for the rest of us, as you

haven't offered to throw sackfuls of money at us poor people helping you

for free and fun.

Thank you to Scott and Ran for figuring out a diagram with all
compulsories including the required items for remote hosts (which are
not in the documentation).  

Personally I think this is very helpful.  

I don't know if that was a joke but either way, I think it's rude to
tell someone that what they need/want to understand is not important to
anyone else.  It's definitely not true, otherwise these lists wouldn't
exist.
