Cleanup (#5)

- Update formatting for stub files
- Update docs

While original project, Profanity, provides valuable basis for this
fork, we are not affiliated with the upstream. This commit
is updating documentation to reflect accurate information.

The docs are going to be updated further once the website is created.
