 About |service| |data-lake|
 ---------------------------
 
-Using |service| |data-lake| to ingest your |s3| data into |service| clusters 
-allows you to quickly query data stored in your |aws| |s3| buckets using the 
-:binary:`~bin.mongo` shell, :atlas:`MongoDB Compass <compass-connection>`, and 
-any MongoDB driver.
-
-When you create a |data-lake|, you can grant |service| either read only or read 
-and write access to |s3| buckets in your |aws| account and create a data 
-storage configuration file that maps data from your |s3| buckets to your 
-MongoDB databases and collections.
-
-|service| supports using any M10+ cluster, including Global Clusters, to 
-connect to |data-lakes| in the same project. 
-
-.. note::
-
-   If you update your custom |aws| role |arn|, you must update the |aws|
-   trust policy associated with the role. See the :guilabel:`Configure a 
-   New Data Lake` modal for instructions.
+MongoDB |service| |data-lake| allows you to natively query and analyze data 
+across |aws| |s3| and MongoDB |service|. You can query your richly structured 
+data stored in |json|, |bson|, CSV, TSV, Avro, ORC, and Parquet formats using 
+the |mongo| shell, :dl:`MongoDB Compass <compass>`, or any 
+:driver:`MongoDB driver </>` without data movement or transformation.
+
+|data-lake| Access 
+------------------
+
+When you create a |data-lake|, you grant |service| either read only or 
+read and write access to |s3| buckets in your |aws| account. To access your 
+|service| clusters, |service| uses your existing :manual:`Role Based Access 
+Controls</core/authorization>`. You can view and edit the generated 
+data storage :ref:`configuration file <datalake-configuration-file>` that maps 
+data from your |s3| buckets and |service| clusters to virtual databases and 
+collections.
