+backend deployment with MySQL and a local SMTP catcher. Configure the public
+domain in Dokploy against service `backend` and container port `5555`.
 
-Before deploying, create an Advanced Mount named `config.json` in Dokploy and
-paste the repository `config.json` content into it. The compose file mounts it
-from `../files/config.json` so AutoDeploy does not depend on bind mounts from a
-freshly cloned repository.
+The runtime image includes `config.json`; override environment-specific values
+with Dokploy environment variables. The SMTP catcher service keeps the internal
+name `mailhog` for compatibility, but uses the multi-architecture Mailpit image
+to avoid `exec format error` failures on ARM servers.
 
 Set `MYSQL_PASSWORD`, `MYSQL_ROOT_PASSWORD` and any other environment-specific
 values in Dokploy environment variables.
