 To add node selectors to an existing pod, add a node selector to the controlling object for that pod, such as a `ReplicaSet` object, `DaemonSet` object, `StatefulSet` object, `Deployment` object, or `DeploymentConfig` object.
 Any existing pods under that controlling object are recreated on a node with a matching label. If you are creating a new pod, you can add the node selector directly to the `Pod` spec.
 
+If you use cluster-wide node selectors, when you create a pod in that cluster, {product-title} adds the default node selectors to the pod and schedules the pod on nodes with labels that match the default node selectors and the pod node selectors.
+
 You can add labels to a node or machine config, but the labels will not persist if the node or machine goes down.
 Adding the label to the machine set ensures that new nodes or machines will have the label.
