 To use your own container image, you can override values. Please refer to the
 [Container image](../build/container-image.md) section for instructions about

 installation with that image can be done with the following command:
 
 ```bash
-helm install lockc contrib/helm/lockc/ --namespace kube-system \
+helm install lockc lockc/lockc --namespace lockc \
