+You can override the default configurations for some specific deployments by modifying the `deployments` spec in the `KnativeServing` custom resource (CR). Currently, overriding default configuration settings is supported for the `resources`, `replicas`, `labels`, `annotations`, and `nodeSelector` fields.
 
 In the following example, a `KnativeServing` CR overrides the `webhook` deployment so that:
 
+* The deployment has specified CPU and memory resource limits.
 * The deployment has 3 replicas.
-* The label is set to `example-label: label`.
-* The label `example-label: label` is added.
+* The `example-label: label` label is added.
+* The `example-annotation: annotation` annotation is added.
 * The `nodeSelector` field is set to select nodes with the `disktype: hdd` label.
