A late followup on this. Is the "How a committer develops on MXNet" documented anywhere? Staging/master etc? The more complex the development process, the harder it is for a newcomer to get involved on the project. I couldn't find it on the website/github.
(I'd also note that the 'how to modify the website/documentation' also needs to be documented) I'd suggest that the how-to-dev doc also explain why it's bad for master to not build. One could argue that, outside of when a release is being made, master is not important to our users. Yes it should build, but an accident should only affect those who have put themselves on the bleeding edge.
