I think the "master" should be the wiki
For me, Yorik's opinion is 'master' here
. Also the reason is good:
When 0.17 will be out, a good part of the book will be outdated. I'm not sure at all I'll have time to change the book, so it has more chances to keep up to date on the wiki...
But, if you really plan to have the whole book reviewed
make it reviewed by a native english speaker who has experience in the publishing business.
I think we may have many other small changes upcoming. Do you intend to edit the wiki then, and use the wiki as the basis for publishing? This is risky, as the wiki is by nature constantly evolving. You need a frozen version for publishing. So I would suggest to incorporate the part you think meaningful of my comments (many are typos or straightforward errors so probably not much to discuss there) as well as your reviewer's version in the master (github for the moment). BTW I'm sorry I don't know any experienced native speaker that could do the job (more than in the publishing, he/she probably should have some CAD experience, as the language is technical here, even if the book is aimed at novices - but not only!)
I can help there as well for my part, as soon as you review my comments, forking on github (silly me, I had that intention at first, then I was misled by quickly looking at gitbook in thinking there was no github source attached).
