+
+=============
+Run a Command
+=============
+
+You can run a MongoDB command directly on a database by calling the ``command()``
+method on a database connection instance.
+
+To run a command, call the ``command()`` method and pass it a document that
+contains the command and its parameters.
+
+Example
+-------
+
+This usage example performs the following actions on the database connection
+instance that uses the ``sample_mflix`` database:
+
+- Creates a database connection instance that references the ``sample_mflix`` 
+  database
+- Specifies a command to retrieve a list of collections and views in the
+  ``sample_mflix``  database
+- Prints the value of the ``name`` field of each result returned by the command
+
+The example calls the ``command()`` method to run the ``listCollections`` command. This method
+returns a cursor that contains a result document for each collection in the database.
