+
+podman / docker - use the same arguments, replace podman with docker if needed.

+If desired, change the host port, which is the first port listed below. eg; To use local port 4000 change the argument to -p 4000:3000, which maps your host port 4000 to the container port 3000
+
+```bash
+podman run -d -p 3000:3000 your-image-name
+```
