# Contributing

We welcome contributions in the form of pull requests.

If proposing changes to package source code, please run the test suite in `python2` and `python3` by running `pytest` or `python setup.py test` from within the repository root.

If using `pytest` directly, we suggest first activating the appropriate Python version's virtual environment and running `pip install --upgrade ./`.
Otherwise, simply specify the appropriate Python version, i.e. `python2 setup.py test` or `python3 setup.py test`.
