I agree that once there is enough material to motivate a separate document, we should separate development and process into two different documents. And once there's enough material to motivate separating HotSpot and libraries development we can do that as well. At the moment I don't think there's enough to motivate that new document though. Even if we move the build section as well, that's pretty much it - building and a brief HotSpot logging.

If more people volunteer to update and move information from the wiki that could clearly happen pretty soon though.
