I skimmed the stuff and had only 2 places where we may disagree and a few typos.
I will give it a detailed review at the weekend and note what I found.
There where a few places where it may be that I didn't know an english idiom but will list it nevertheless.
I read my bit of english and if I didn't know it others may miss it, too.
It encourages me to finally publish some of my esp8266 notes, too.
Not as literature like yours but just notes.
I plan to put them online as a github wiki for the following reason:
It's easy for everone to make a copy for personal use or clone it to whatever git repo seems fit.
alonewolfx2 did a good job providing this forum for us and the wiki but does not respond
to requests like fixing the message template that combines "by" and the user name.
I think I tried it 3 times on different ways and others posted about the problem, too, without success.
So I am hesitating to put too much effort in some php wiki where I don't see a way to get the content as a whole
without some kind of backup. If he decides to put it down, its gone.
If it's only a few pages it's probably ok to manually duplicate it.
I think we saw bigger elephants die.
