   1. As part of the first phase of the multi-phased release process, a validating
 webhook server has been added. This server will perform additional validation (strict) which was not done during the beta release of volume snapshots. It will prevent the cluster from gaining (via create or update) invalid objects.
-  2. The controller will label objects which fail the additional validation. The label "snapshot.storage.kubernetes.io/invalid-snapshot-content-resource" will be added to invalid VolumeSnapshotContent objects. The label "snapshot.storage.kubernetes.io/invalid-snapshot-resource" will be added to invalide VolumeSnapshot objects.
+  2. The controller will label objects which fail the additional validation. The label "snapshot.storage.kubernetes.io/invalid-snapshot-content-resource" will be added to invalid VolumeSnapshotContent objects. The label "snapshot.storage.kubernetes.io/invalid-snapshot-resource" will be added to invalid VolumeSnapshot objects.
 
   The combination of 1 and 2 will allow cluster admins to stop the increase of invalid objects, and provide a way to easily list all objects which currently fail the strict validation. It is the kubernets distribution and cluster admin's responsibility to install the webhook and to ensure all the invalid objects in the cluster have been deleted or fixed. See the KEP at https://github.com/kubernetes/enhancements/blob/master/keps/sig-storage/177-volume-snapshot/tighten-validation-webhook-crd.md ([#353](https://github.com/kubernetes-csi/external-snapshotter/pull/353), [@AndiLi99](https://github.com/AndiLi99))
 
 ### Snapshot Controller
 
-- With the addition of the validating webhook server, the snapshot controller is modified to label objects which fail the additional validation. The label "snapshot.storage.kubernetes.io/invalid-snapshot-content-resource" will be added to invalid VolumeSnapshotContent objects. The label "snapshot.storage.kubernetes.io/invalid-snapshot-resource" will be added to invalide VolumeSnapshot objects.
