 There is a Helm history limit of 10 revisions, but this limit applies only to revisions in a non-transient state.
 If you see multiple revisions in a pending-rollback or pending-upgrade state in the Helm history output, run the script below to clean up the Helm history on the cluster:
 ```
 #!/bin/bash
 
 # Set release name and namespace
-RELEASE_NAME=$1 # release_name is the name of the azure ml extension helm release 
+RELEASE_NAME=$1 # release-name is the name of the azure ml extension helm release 
 NAMESPACE=$2 # namespace is the azure ml extension's namespace. Default value is azureml 
 
 # Validate input
