Documentation, or a more visible link to it if it exists

[peter1rhodes]

I'd like to use this library, but I can't see any documentation or homepages linked in Github, nor on PyPI. The only demo script (copied below) has no explanations, and does not work anyway because of a bug that has a fix (#71 ) that apparently has been waiting to be merged for two years.

It may be that there is documentation! In which case, my ticket would be a suggestion for more visible links to it.
