-Extensive inheritance from the provided `controller` module (a C interface) will be required, so it is useful to set up a proper development environment (consider using a virtual environment and an IDE) and set the robot controller to `<extern>` in Webots.

+## Development
+
+It is useful to set up a proper development environment with the provided
+`controller` module (a C interface) included in your linter/IDE and set the
+robot controller to `<extern>` in Webots for debugging. More information at
+https://cyberbotics.com/doc/guide/using-your-ide?tab-language=python. The main
+steps for PyCharm are:
 
 1. Configure the virtual environment in _Project Interpreter_
-2. Add the correct Webots `controller` directory (depending on your system and Python configuration, `controller/_controller.so` is slightly different) as _Content Root_ under _Project Structure_
-3. Create a _Run/Debug Configuration_, setting the [relevant environment variables](https://cyberbotics.com/doc/guide/running-extern-robot-controllers?tab-language=python)

-If you still prefer to use the system Python or run controller directly from Webots, have a look at https://cyberbotics.com/doc/guide/using-python. This is especially important for people using MacOS and Homebrew, you may need to set the full path to your Python interpreter (get it by `which python3`).
