Readthedocs build fix and updated sphinx documentation

I was told to use Twine at Pycon for uploading packages to PyPI. I just set it up and ran into a few issues. I thought it would be helpful to get readthedocs setup with more detailed documentation. 
So, I have no opinions on the content but I do have an issue with copying and pasting the README in here when there are rST directives that do the same thing without duplicating content
