Looks good to me. If we are updating these guides, can we add a sentence in 2 player to say 11 regions vrs 14 regions vrs 17 regions blah de blah de blah... I think that's become standard in these guides. And there may be a few more points like that. Also how about looking at the few missing apostrophes etc.
I am 99% sure it's not on to link to an external site from an official CC doc like this guide will be - but never mind the quip works better without a link.
