* Move most reference and cookbook documentation in README.md into
the "reference" and "cookbook" sections of the generated documentation,
respectively.
* Try to steer people to the generated docs inside the README.md (since
it is now basically just a set of quickstart instructions)
* Provide a bit of guidance that this repository isn't great for 3rd
party contributors in a new CONTRIBUTING.md.
