 You can lint your code locally by running ``flake8 .`` from the root of the repository.
 Integrating ``flake8`` into your workflow is recommended, there are plugins available for most popular `IDEs <https://foxmask.trigger-happy.eu/post/2016/02/17/pycharm-running-flake8/>`_ and `text-editors <https://github.com/nvie/vim-flake8>`_!
