IMHO the CONTRIBUTING.md is something that can be fairly simple. The
important things is that it should cover directly are

 - How to submit patches
 - How to report issues
 - How to comply with the DCO

Then it should provide links to information about coding style,
information around testing, information about platform portability
expectations, and other important reference material that might be
relevant.

We can certainly split up / re-organize hacking.html more generally,
but I don't think that's a strict pre-requisite for adding a simple
CONTRIBUTING.md file.
