missing README file

[anthrotype]

Does anybody fancy adding a short README text file at the top-level of the repository?

I would like to use that for the long_description in setup.py, so that it can also be used for the project homepage on PyPI.

If it is formatted in reStructuredText instead of markdown it'd be even better, as currently PyPI cannot render .md files while Github can render .rst ones just fine.

It's easy to convert md to rst, e.g. with pandoc:
pandoc --from=markdown --to=rst --output=README.rst README.md
