+## Running nginx as a non-root user
+To run the image as a less privileged user using the `nginx` user, do the following:
+```ShellSession
+$ podman run -it --user nginx --rm -p 8080:8080 -v /path/to/html/:/srv/www/htdocs/:Z -v $PWD/nginx.conf:/etc/nginx/nginx.conf:Z registry.opensuse.org/opensuse/nginx:1.29

+**Note:** When running as the `nginx` user the default port is 8080.
