- [ ] Bump the version and commit it
  - [ ] Remove `dev0` from the version in [``__init__.py`` ``__version__``](https://github.com/pandas-dev/pydata-sphinx-theme/blob/master/pydata_sphinx_theme/__init__.py#L11)
  - [ ] Make a release commit: ``git commit -m 'RLS: v0.2.0'``
  - [ ] Push the RLS commit ``git push upstream master``
- [ ] Create sdist and wheel and upload to PyPI: 
  - [ ] ``python setup.py sdist``
