 This example shows you how to create and consume a `PersistentVolume` from an existing EBS volume with static provisioning.
 
 1. Edit the `PersistentVolume` manifest in [pv.yaml](./manifests/pv.yaml) to include your `volumeHandle` EBS volume ID and `nodeSelectorTerms` zone value.
+    The `StorageClass` on the `PersistentVolumeClaim` and `PersistentVolume` must match. If you have a default storage class, this means you must explicitly set `spec.storageClassName` to `""` in the [PVC manifest](manifests/claim.yaml#L6) if the PV doesn't have a `StorageClass`.
+    The [`spec.volumeName` field](manifests/claim.yaml#L7) of the PVC must match the [name of the PV](manifests/pv.yaml#L4) for it to be selected.
