 - `--gpus all` enables GPU acceleration.
-- `-p 8789:8789` exposes the trainer UI and captured-audio endpoint.
+- `--network host` lets the container receive mDNS/zeroconf traffic for ESPHome auto-detect.
 - `-v $(pwd):/data` persists models, downloaded voices, datasets, samples, and firmware caches.
 
+Host networking is recommended for the Firmware tab's mDNS device discovery. Manual IP flashing and captured-audio uploads can still work without host networking if the trainer port is reachable, but auto-detect may not see devices from Docker bridge networking.
