I was going through the code and I found some nits in the prompt
code (using `.get` with a default value on dicts) and decided to
take the occasion to setup some tests.

I've updated the README accordingly (tests need `pytest` and
`pytest-mock` to be installed).

The `README.md` has been reformated using a markdown linter, I hope you
don't mind.
