+Contributing
+============
+
+Any contributions should follow the following pattern:
+
+1. Make a feature or bugfix branch, e.g.,
+   ``git checkout -b my_new_feature``
+2. Make your changes in that branch
+3. Ensure you bump the version number in ``searchtweets/_version.py`` to
+   reflect your changes. We use `Semantic
+   Versioning <https://semver.org>`__, so non-breaking enhancements
+   should increment the minor version, e.g., ``1.5.0 -> 1.6.0``, and
+   bugfixes will increment the last version, ``1.6.0 -> 1.6.1``.
+4. Create a pull request
+
+After the pull request process is accepted, package maintainers will
+handle building documentation and distribution to Pypi.
+
+For reference, distributing to Pypi is accomplished by the following
+commands, ran from the root directory in the repo:
+
+.. code:: bash
+
+    python setup.py bdist_wheel
+    python setup.py sdist
+    twine upload dist/*
