 # Running The Script
 There are two main ways to run the script. The first is to just provide
-the script with a directory to start from. The script will then read
-every file in that directory and all subdirectories. The second way
-is to provide the script with the FSx for ONTAP file system data endpoint

 if it isn't already mounted. If it does mount it, it will mount it read-only
 and unmount when it is done.

 Where:
   -f filesystem_endpoint - Is the hostname or IP address of the FSx for ONTAP file system.
-  -v volume_name - Is the ID of the volume.
+  -v volume_name - Is the name of the volume.
   -n nfs_type - Is the NFS version to use. Default is nfs4.
   -d directory - Is the root directory to start the process from.
   -t max_directory_threads - Is the maximum number of threads to use to process directories. The default is 10.
