 `m3u8downloaderd` is an in-memory local-network web interface for the adjacent
 `N_m3u8DL_py` package. It requires Python 3.10+ and a system `ffmpeg`.
 
+## Docker
+
+From the repository root, start the service and build its image when needed:
+
+```bash
+docker-compose up
+```
+
+Open `http://127.0.0.1:8000`. Downloaded files are written to the repository's
+`downloads/` directory. Use `docker-compose down` to stop the service.
+
 Install both local packages into the same environment:
 
 ```bash
