From the announcement <http://blog.readthedocs.com/securing-subdomains/>:
> Starting today, Read the Docs will start hosting projects from
> subdomains on the domain readthedocs.io, instead of on readthedocs.org.
[...]
> Projects will automatically be redirected, and this redirect will
> remain in place for the foreseeable future. Still, you should plan on
> updating links to your documentation after the new domain goes live.

A CONTRIBUTING.rst is added to the root of the repo, as Github
automatically recognizes this for incoming PRs

docs, which is restructured to refer to this file instead for
contribution guidelines
