+Set ``maxTimeMS`` for Aggregation Queries
+-----------------------------------------
+
+Use the ``maxTimeMS`` parameter on the :guilabel:`Aggregations` tab to 
+specify an upper time limit in milliseconds on the aggregation pipelines
+that run in |compass-short|.
+
+To enable ``maxTimeMS`` for aggregation operations:
+
+.. procedure::
+   :style: normal
+
+   .. step:: On the :guilabel:`Aggregations` tab, click 
+      :guilabel:`More Options`.
+
+      .. figure:: /images/compass/agg-builder-click-more-options.png
+         :alt: Toggle more options
+
+   .. step:: Enter a value next to :guilabel:`Max Time MS` to set a 
+      maximum amount of time in milliseconds that an aggregation 
+      pipeline can run. For a ``5`` second limit, enter ``5000``.
+
+      .. figure:: /images/compass/agg-builder-enter-maxtime-ms.png

+
+      If your aggregation operation goes over the time limit, 
+      |compass-short| raises the following error:
