+## Continuous Deployment
+
+`cd-watch.sh` checks `origin/main` and runs `deploy.sh` when the remote revision changes.
+
+```sh
+sudo ./cd-watch.sh
+```
+
+The server cron runs this once per minute.
+
 ## Paths
 
 - App: `/volume2/homes/whitekomani/photo-request-service`
 - Config: `.env`
 - DB: `data/db.json`
+- Deploy log: `data/deploy.log`
 - Uploads: `/volume2/AKA Drive/사진 받기`
 
 Each request creates its own folder under the upload directory.
