 ## How CMK works in Azure Monitor
 
-Azure Monitor leverages system-assigned managed identity to grant access
-to your Azure Key Vault. System-assigned managed identity can only be
-associated with a single Azure resource while the identity of the Log Analytics cluster is supported at the cluster level. This
-dictates that the CMK capability is delivered on a dedicated Log Analytics cluster. To support CMK on multiple workspaces, a new Log Analytics
-*Cluster* resource performs as an intermediate identity connection
-between your Key Vault and your Log Analytics workspaces. The Log Analytics cluster storage uses the
-managed identity that\'s associated with the *Cluster* resource to
-authenticate to your Azure Key Vault via Azure Active Directory. 
-After CMK configuration, any data ingested to workspaces associated to your *Cluster* resource gets encrypted with your key in Key Vault. You can disassociate workspaces from the *Cluster* resource at any time. New data gets ingested to Log Analytics storage and encrypted with Microsoft key, while you can query your new and old data seamlessly.
+Azure Monitor leverages system-assigned managed identity to grant access to your Azure Key Vault. 
+System-assigned managed identity can only be associated with a single Azure resource while the identity of the Log Analytics cluster is supported at the cluster level -- This dictates that the CMK capability is delivered on a dedicated Log Analytics cluster. To support CMK on multiple workspaces, a new Log Analytics *Cluster* resource performs as an intermediate identity connection between your Key Vault and your Log Analytics workspaces. The Log Analytics cluster storage uses the managed identity that\'s associated with the *Cluster* resource to authenticate to your Azure Key Vault via Azure Active Directory. 
+
+After CMK configuration, any data ingested to workspaces associated to your *Cluster* resource gets encrypted with your key in Key Vault. You can disassociate workspaces from the *Cluster* resource at any time. New data gets ingested to Log Analytics storage and encrypted with Microsoft key, while you can query your new and old data seamlessly.
