+The ``privateendpoint regionalmode describe`` command retrieves whether 
+the regionalized private endpoint setting is enabled or disabled for an 
+|service| project. If enabled, this setting lets you use regionalized 
+private endpoints for multi-region sharded clusters. You can also 
+retrieve the regionalized private endpoint setting through the 
+|service| :atlas:`UI </security-private-endpoint/#regionalized-private-endpoints-for-multi-region-sharded-clusters>` or 
+:atlas:`API </reference/api/private-endpoints-get-regional-mode/>`.
