-## Compilation / Release
+### Coding style

+Use PEP8 except where Qt bindings are used (`gui.py`). To check use
+```
+$ pep8 --show-source --ignore=E501 moodle.py muddle.py <more files...>
+```
+
+### Compilation / Release
 To create an executable you need PyInstaller, you can get it with
 ```
 $ pip3 install pyinstaller
