Is your ultimate goal to break into the tech industry? If so, I'd spend a bit more time getting some actual working pieces of code on your GitHub. Editing documentation is a noble deed, but as an interviewer it wouldn't do much for me in assessing your skills.

I know it takes a lot of effort as well as luck in landing that first entry-level job so all I can say is to keep knocking, but also be prepared to show something tangible. Anyone can talk all day about their awesome work ethics but it's another thing to be able to prove it by presenting a polished (for a junior) software.
