+## System Dependencies for Audio Streaming
+
+This project uses the `sounddevice` Python package, which requires the PortAudio library to be installed on your system.
+
+### Install PortAudio on Debian/Ubuntu/Raspberry Pi OS
+
+Before running the application, install the following system packages:
+
+```bash
+sudo apt-get update
+sudo apt-get install libportaudio2 libportaudiocpp0 portaudio19-dev
+```
+
+If you encounter an error like `OSError: PortAudio library not found` when running the Python scripts, make sure you have installed these dependencies.
