+## Running via Container
 
-Requires Node.js 12 and the Yarn package manager installed
+This application is setup to publish a container image to `ghcr.io/discohook/site:latest`. This image can be run with [podman](https://podman.io/), [docker](https://www.docker.com/), or another service compliant with the [OCI](https://opencontainers.org/). The image can be run from the command line with the following command or in the desktop guis ([podman desktop guide](https://podman-desktop.io/docs/working-with-containers/starting-a-container))
+```sh
+# Replace 'podman' with 'docker' if using that, the command is equivalent
+# Add --rm if you want the container to be removed automatically after being stopped
+# If necesary, change the second 3000 to change which port on the local computer the app is bound to
+podman run -d -p 3000:3000 ghcr.io/discohook/site:latest
