Too specific, does the guide actually work?
Hi, Github links here. But this describes making pull requests for pywikibot on GitHub. What makes them actually turn into gerrit review requests? Looking at this pull request, legoktm "uploaded this into gerrit at https://gerrit.wikimedia.org/r/#/c/182561/ for review", a completely manual process.
This page should be about GitHub -> Gerrit integration in general, which is phab:T37497, with your notes as a subsection about "Here's how to contribute to a Wikimedia project on GitHub, but your pull requests won't show up in gerrit" (yet)..
