+### Debugging
+
+After flashing the new features, it’s recommended to capture detailed logs from the serial port.
+
+First, make sure all required Python packages are installed:
+
+```python
+python3 -m pip install serial colorama matplotlib
+```
+after that run the script:
+```sh
+python3 scripts/debugging_monitor.py
+```
+This was tested on Debian and should work on most Linux systems. Minor adjustments may be required for Windows or macOS.
