-| 80 | TCP | Some useful details |
+| 2525 | TCP | SMTP |
+| 9904 | TCP | HTTP server with Prometheus metrics |
 
 ## Volumes
 
 | Container path | Description |
 |------------|---------------|
-| /config | Some useful details |
+| /haraka | Haraka root directory |
 
 ## Security
-The container is regularly scanned for vulnerabilities and updated. Further info can be found in the [Security tab](https://github.com/homecentr/docker-$$IMAGE_NAME$$/security).
+The container is regularly scanned for vulnerabilities and updated. Further info can be found in the [Security tab](https://github.com/homecentr/docker-haraka-relay/security).
 
 ### Container user
-The container supports privilege drop. Even though the container starts as root, it will use the permissions only to perform the initial set up. The $$IMAGE_NAME$$ process runs as UID/GID provided in the PUID and PGID environment variables.
-
-:warning: Do not change the container user directly using the `user` Docker compose property or using the `--user` argument. This would break the privilege drop logic.
+The container runs as a non-root user with UID/GID 1000 by default.
