+The `.env` file is **not** committed to the repository. The deploy script automatically creates it with default values (`PUID=0`, `PGID=0`, `TZ=America/New_York`) on first run if it does not already exist. To customise, edit it on the droplet after the first deployment:
 
 ```bash
 # On the droplet
