Suggest change of main title...

I think this is a great idea. But the title (in index.rst) as it appears in other documents is IMHO not very descriptive. For matplotlib it says "Working with Matplotlib source code". That is vague, and doesn't indicate anything about "git" or "GitHub" to me and I never thought to click on that link (particularly when "Contributing" is so prominent).

I'd suggest something with GitHub in it: i.e. "Working with Matplotlib code using git and GitHub" or "Using git and Github to contribute to Matplotlib".
