First version of Read the Docs

I'm getting the feeling that we're talking about different things. I only suggest that you add the following lines 

```
sphinx_rtd_theme
sphinx-autobuild
```

to `https://github.com/mozilla/oneanddone/blob/master/requirements/dev.txt`

and remove the `docs/requirements.txt` file https://github.com/mozilla/oneanddone/pull/199/files#diff-93bd81aa3a2f0c02728220a6b46fb58dR1

I do not suggest that you change something in the code. Does this help a bit?
