+Generate {+data-lake-short+} Configuration
+------------------------------------------
+
+You can run the ``storageGenerateConfig`` command to regenerate a 
+{+data-lake-short+} :ref:`configuration <datalake-configuration-file>`. 
+The command returns an automatically generated :ref:`configuration 
+<datalake-configuration-format>`, which you can then modify and 
+:ref:`upload <datalake-setstorageconfig>`. In the automatically 
+generated configuration, {+data-lake-short+} regenerates a 
+:ref:`database <datalake-databases-reference>` for each :ref:`store 
+<datalake-stores-reference>`:
+
+- The :datalakeconf:`databases.[n].name` will be the same as the 
+  :datalakeconf:`stores.[n].name` that it maps to.
+- Each database will contain up to 3 collections and a wildcard (``*``) 
+  collection.
+
+As a result, the :ref:`databases <datalake-databases-reference>` 
+array in the generated configuration might be different from the 
+:ref:`databases <datalake-databases-reference>` array in your existing 
+configuration. 
+
+.. note::
+
+   You must have the ``storageSetConfig`` privilege to run the 
+   ``storageGenerateConfig`` command. The :atlas:`atlasAdmin 
+   <security-add-mongodb-users/#atlasAdmin>` role has the 
+   ``storageSetConfig`` privilege by default.
+
+To generate a {+data-lake-short+} configuration, connect to the {+data-lake-short+} 
+and run the following database commands: 
+
+.. code-block:: javascript 
+
+   use admin 
+   db.runCommand( { "storageGenerateConfig" : 1 } )
