Thanks for your interest in contributing to django-markitup!
Features and bugfixes that involve modifying Python code should be accompanied by tests in tests/tests.py, and all existing and new tests should pass. To run tests on the full matrix of all supported Python and Django versions, pip install tox and then run tox. This requires that you have python2.6 and python2.7 available on your system; if you don't have one or the other, the tests for that Python version will fail. Please note in your pull request what version(s) of Python you successfully ran the tests with.
If your change is a new feature or has user-facing impact, please modify or add to the documentation in README.rst as needed.
The bundled MarkItUp! JS lib markitup/static/markitup/jquery.markitup.js and the toolbar sets in markitup/static/markitup/sets are bundled directly from upstream at http://markitup.jaysalvat.com/downloads/. Pull requests to update to more recent code from upstream are welcome, but please do not submit pull requests with other changes to these files; I don't want to take on responsibility for maintaining forked versions.
Feel free to add your name to AUTHORS.rst (alphabetical order) and summarize your change with a brief entry in CHANGES.rst as part of your pull request.
