 Python documentation is generated by [Sphinx](http://sphinx-doc.org/). A fully dynamic Sphinx configuration is available: [config](https://github.com/tue-robotics/tue_documentation_python.git). Add this to your package as a submodule,
 
 ```bash
-git submodule add https://github.com/tue-robotics/tue_documentation_python.git FOLDER -b master
+git submodule add -b master https://github.com/tue-robotics/tue_documentation_python.git FOLDER
 ```
 
 Use `docs` or `docs/python` for `FOLDER`. Preferably `docs` is used in packages with only Python and `docs/python` if also other programming languages are used.
