 mvn clean package -Doperator -Dquarkus.container-image.build=true
 ```
 
+This will build a container image from `src/main/docker/Dockerfile.jvm`, using `docker` by default. `podman` is also supported if you do these steps beforehand:
+
+- Follow [this guide](https://quarkus.io/guides/podman#setting-docker_host-on-linux) to enable the podman user socket
+- Set the `DOCKER_HOST` environment variable to point at this user socket. For example: `DOCKER_HOST=unix:///run/user/1000/podman/podman.sock`.
+- You may also have to set `QUARKUS_DOCKER_EXECUTABLE_NAME=podman`

 ## Configuration
 
 The Keycloak image can be configured, when starting the operator, using the Java property:
