+Create a Materialized View in the {+atlas+} UI 
+-------------------------------------------------------
+
+The example in this section uses the :atlas:`sample movies dataset 
+</sample-data/sample-mflix/>`. To learn how to load the sample dataset 
+into your {+atlas+} deployment, see :atlas:`Load Sample Data 
+</sample-data/#std-label-load-sample-data>`.
+
+To create a materialized view in the {+atlas+} UI, follow these
+steps:
+
+.. procedure:: 
+   :style: normal
+
+   .. step:: Navigate to the collection
+
+      a. In the {+atlas+} UI, click :guilabel:`Database` in the sidebar.
+      #. For the database deployment that contains the sample data,
+         click :guilabel:`Browse Collections`.
+      #. In the left navigation pane, select the
+         :guilabel:`sample_training` database.
+      #. Select the :guilabel:`grades` collection.
+
+   .. step:: Click the :guilabel:`Aggregation` tab
+
+   .. step:: Click :guilabel:`Add Stage`
+
+   .. step:: Select an aggregation stage from the :guilabel:`Select` drop-down menu
+
+      The aggregation stage transforms the data that you want to save as
+      a view. To learn more about available aggregation stages, see 
+      :ref:`agg-pipeline-quick-ref`.
+
+      For this example, add a new field with the :pipeline:`$set` stage:
+
+      a. Select :pipeline:`$set` from the :guilabel:`Select` drop-down
+         menu.
+      #. Add the following syntax to the aggregation pipeline 
+         editor to create an average score across all ``score``
+         values in the ``scores`` array within the ``grades``
+         collection:
+
+         .. code-block::
+
+            {
+              averageScore: { $avg: "$scores.score" }
+            }
+
+         {+atlas+} adds the ``averageScore`` value to each document.
+
+   .. step:: Click :guilabel:`Add Stage`
+
+   .. step:: Add the ``$out`` stage
+      
+      a. Select the :pipeline:`$out` stage from the :guilabel:`Select` 
+         drop-down menu.
+      #. Add the following syntax to the aggregation pipeline
+         to write the results of the pipeline to the ``myView``
+         collection in the ``sample_training`` database:
+
+         .. code-block::
+
+            'myView'
+
+      #. Click :guilabel:`Save Documents`.
+
+      The :pipeline:`$out` stage writes the results of the
+      aggregation pipeline to the specified collection, which creates
+      the view. To learn more, see :pipeline:`$out`.
+
+      Refresh the list of collections to see the ``myView`` collection.
+
+      To learn how to query the ``myView`` collection in the {+atlas+}
+      UI, see :atlas:`View, Filter, and Sort Documents 
+      </atlas-ui/documents/#view--filter--and-sort-documents>` in the
+      {+atlas+} documentation.
