+Disable Use of id Field Name Conversion
+---------------------------------------
+
+Starting in {+odm-long+} v5.0, ``id`` is an alias for the ``_id`` field
+in MongoDB documents, and the library automatically converts ``id``
+to ``_id`` for both top level and embedded fields when querying and
+storing data.
+
+When using {+odm-long+} v5.3 or later, you can disable the automatic
+conversion of ``id`` to ``_id`` for embedded documents. To do so,
+perform either of the following actions:
+
+1. Set the ``rename_embedded_id_field`` setting to ``false`` in your
+   ``config/database.php`` file:
+
+   .. code-block:: php
+      :emphasize-lines: 6
+
+      'connections' => [
+          'mongodb' => [
+              'dsn' => 'mongodb+srv://mongodb0.example.com/',
+              'driver' => 'mongodb',
+              'database' => 'sample_mflix',
+              'rename_embedded_id_field' => false,
+              // Other settings
+          ],
+      ],
+
+#. Pass ``false`` to the ``setRenameEmbeddedIdField()`` method in your
+   application:
+
+   .. code-block:: php
+
+      DB::connection('mongodb')->setRenameEmbeddedIdField(false);
