+### Shortcut configuration with Python
+
+[shortcut_listener.py](shortcut_listener.py) is a script to listen to a specific shortcut to kill any active game started by the launcher. It communicates with the launcher using websockets (yes a bit overkill).
+
+Requires python 3.10.x with the following package `asyncio, websockets, keyboard`
+
+```
+pip install asyncio, websockets, keyboard
+```
+
+The python script will be launched automatically by the app if you have a `shortcut_kill_game` set in [launcher_config.ini](launcher_config.ini).
