 If you would like to see the feature in action and verify it works fine in your cluster here's what you can try:
 
 1. Define a basic PersistentVolumeClaim:
-```yaml
-apiVersion: v1
-kind: PersistentVolumeClaim
-metadata:
-  name: pvc-1
-spec:
-  accessModes:
-  - ReadWriteOnce
-  resources:
-    requests:
-      storage: 1Gi
-```
+
+   ```yaml
+   apiVersion: v1
+   kind: PersistentVolumeClaim
+   metadata:
+     name: pvc-1
+   spec:
+     accessModes:
+     - ReadWriteOnce
+     resources:
+       requests:
+         storage: 1Gi
+   ```
 
 2. Create the PersistentVolumeClaim when there is no default StorageClass. The PVC won't provision or bind (unless there is an existing, suitable PV already present) and will remain in <code>Pending</code> state.
-```
-$ kc get pvc
-NAME      STATUS    VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS   AGE
-pvc-1     Pending   
-```
+
+   ```
+   $ kc get pvc
+   NAME      STATUS    VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS   AGE
+   pvc-1     Pending   
+   ```
 
 3. Configure one StorageClass as default.
-```
-$ kc patch sc -p '{"metadata":{"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
-storageclass.storage.k8s.io/my-storageclass patched
-```
+
+   ```
+   $ kc patch sc -p '{"metadata":{"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
+   storageclass.storage.k8s.io/my-storageclass patched
+   ```
 
 4. Verify that PersistentVolumeClaims is now provisioned correctly and was updated retroactively with new default StorageClass.
-```
-$ kc get pvc
-NAME      STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS      AGE
-pvc-1     Bound    pvc-06a964ca-f997-4780-8627-b5c3bf5a87d8   1Gi        RWO            my-storageclass   87m
-```
+
+   ```
+   $ kc get pvc
+   NAME      STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS      AGE
+   pvc-1     Bound    pvc-06a964ca-f997-4780-8627-b5c3bf5a87d8   1Gi        RWO            my-storageclass   87m
+   ```
