 ## Building Docker image
 
+The image can be built with either `docker` or `nerdctl` depending on which container environment you have installed. Here I show the example using
+Racher Desktop configured to use `nerdctl`.

 ```bash
+mvn clean package -DskipTests
 nerdctl build -t dataone-index-worker:2.4.0 -f docker/Dockerfile --build-arg TAG=2.4.0 .

+nerdctl run --rm dataone-index-worker:2.4.0
