 ## Sample Usage
 
 ### Admission Controllers
 
 Defining a mutation or validation controller is simple as:

+  @Singleton
+  @Named(MUTATING_CONTROLLER)
+  public AdmissionController<Pod> mutatingController() {
+    return new AdmissionController<>((resource, operation) -> {
+      if (resource.getMetadata().getLabels() == null) {
+        resource.getMetadata().setLabels(new HashMap<>());
+      }
+      resource.getMetadata().getLabels().putIfAbsent(APP_NAME_LABEL_KEY, "mutation-test");
+      return resource;
+    });
+  }

+  @Singleton
+  @Named(VALIDATING_CONTROLLER)
+  public AdmissionController<Pod> validatingController() {
+    return new AdmissionController<>((resource, operation) -> {
+      if (resource.getMetadata().getLabels() == null
+              || resource.getMetadata().getLabels().get(APP_NAME_LABEL_KEY) == null) {
+        throw new NotAllowedException("Missing label: " + APP_NAME_LABEL_KEY);
+      }
+    });
+  }
+
+```

+What can be simply used in an endpoint:
+
+```java
+  @POST
+  @Path(MUTATE_PATH)
+  @Consumes(MediaType.APPLICATION_JSON)
+  @Produces(MediaType.APPLICATION_JSON)

+  @Produces(MediaType.APPLICATION_JSON)
+  public AdmissionReview validate(AdmissionReview admissionReview) {
