+Contributing
+-------------
+
+Before you contribute code to this project, please make sure it conforms to the project coding standards
+and that the project unit tests still pass. The easiest way to contribute is to work on a checkout of the repository,
+or your own fork. If you do this, you can run the following commands to check if everything is ready to submit:
+
+    cd project
+    pip install -r dev-requirements.pip
+    pytest
+
+Which should give you no failures or errors. You can ignore any skipped tests as these are for external tools.
+

 You can set up your own key combo for this, by going to Preferences -> Key Bindings - User, and adding a command in that huge array: `{ "keys": ["ctrl+alt+f"], "command": "code_formatter" },`. Default keybinding is `ctrl+alt+f`. You can use any other key you want, thought most of them are already taken.
