+      code from the :ref:`ruby-quick-start-download-and-install` step

+      ``movies`` collection in the ``sample_mflix`` database.

+
+   .. step:: Run your {+language+} application
+

+      command to run the application:
+      
+      .. code-block:: none
+
+         ruby quickstart.rb
+
+      The command line output contains details about the retrieved movie
+      document:
+
+      .. code-block:: none
+         :copyable: false
+
+         {"_id"=>BSON::ObjectId('...'), "plot"=>"A young man is accidentally sent
+         30 years into the past in a time-traveling DeLorean invented by his friend,
+         Dr. Emmett Brown, and must make sure his high-school-age parents unite
+         in order to save his own existence.", ...
+         "title"=>"Back to the Future", ...
+
+      If you encounter an error or see no output, ensure that you specified the
+      correct connection string in the ``quickstart.rb`` file and that you loaded the
+      sample data.
+
+After you complete these steps, you have a working application that
+uses the driver to connect to your MongoDB deployment, runs a query on
+the sample data, and prints out the result.
