+## Deployment
+
+Deploy to the Linux server with:
+
+```bash
+bash ./scripts/deploy.sh
+```
+
+The script publishes the app locally, uploads a release to `/root/docker/rpgroller/releases/<UTC timestamp>`, updates `/root/docker/rpgroller/current`, rebuilds the `rpgroller` image, and recreates the `rpgroller` container. The SQLite database is preserved because the container keeps using the existing bind mount at `/root/docker/rpgroller/data`.
+
 Environment overrides:
 
 - Set `ConnectionStrings__RpgRoller` to point at a custom SQLite database.
