 # yt-playlist-radio
 Simple demo of YouTube playlist to m3u playlist, all in about 100 lines of Python.
+
+## How to run?
+First set the environment variables as per `.env.template`, then just run it with gunicorn or something else (gunicorn comes bundled as part of the deps here)
+```bash
+uv sync
+uv run gunicorn -w 4 -b 0.0.0.0:8000 yt_radio:app
+```
