+# Example setup
+
+The CRD must be deployed independently. 
+
+```sh
+kubectl apply -f https://github.com/mnlipp/VM-Operator/raw/main/deploy/crds/vms-crd.yaml
+```
+
+Apart from that, the `kustomize.yaml` defines a namespace for the manager 
+(and the VMs managed by it) and patches the repository PVC to create
+a small volume using a ceph fs.
+
+The `kustomize.yaml` does not include the test VM. Before creating
+the test VM, you will again most likely want to change the
+disk definition. The sample file claims a ceph block device.
