 About |service| |data-lake|
 ---------------------------
 
-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.
+MongoDB |service| |data-lake| allows you to natively query, transform, 
+and move data across |aws| |s3| and MongoDB |service| clusters. 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 </>`.
+
+Sample Uses 
+-----------
+
+You can use {+adl+} to: 
+
+- Convert richly structured MongoDB data into columnar Parquet or CSV 
+  files.
+- `Query across multiple Atlas clusters <https://developer.mongodb.com/how-to/query-multiple-databases-with-atlas-data-lake/?tck=featlearn>`__ 
+  to get a holistic view of your data.
+- Materialize aggregations from MongoDB or |s3| data.
+- Automatically import data from your |s3| bucket into an |service| 
+  cluster.
 
 |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 <datalake-configuration-file>` that maps data from 
-your |s3| buckets and |service| clusters to virtual databases and collections.
