Developing#Updating_sources contains a link that describes how to use the github website to pull recent changes into your fork repository with a merge commit. When I did it my repo de-synced from ZeroK-RTS master making a whole bunch of separate commits by me authored by someone else. When I tried to pull request some changes it resulted in this https://github.com/ZeroK-RTS/Zero-K/pull/3688 where my changes were on top of 400 commits separate from what master was. It would be best to re-write this section to be more clear. For referance, I had bare bones knowlege on how to use git and I've never worked with forks before.
