 # Static Provisioning 
-This example shows how to create and consume persistence volume from exising EBS using static provisioning. 
+This example shows how to create and consume persistent volume from exising EBS using static provisioning.
 
 ## Usage
 1. Edit the PersistentVolume spec in [example manifest](./specs/example.yaml). Update `volumeHandle` with EBS volume ID that you are going to use, and update the `fsType` with the filesystem type of the volume. In this example, I have a pre-created EBS  volume in us-east-1c availability zone and it is formatted with xfs filesystem.
