+
+Extend Third-Party Model Classes
+--------------------------------
+
+You can use {+odm-short+} to extend a third-party model class by
+including the ``DocumentModel`` trait when defining your model class. By
+including this trait, you can make the third-party class compatible with
+MongoDB.
+
+When you apply the ``DocumentModel`` trait to a model class, you must
+declare the following properties in your class:
+
+- ``$primaryKey = '_id'``, because the ``_id`` field uniquely
+  identifies MongoDB documents
+- ``$keyType = 'string'``, because {+odm-short+} casts MongoDB
+  ``ObjectId`` values to type ``string``
+
+Extended Class Example
+~~~~~~~~~~~~~~~~~~~~~~
+
+This example creates a ``Planet`` model class that extends the
+``CelestialBody`` class from a package called ``ThirdPartyPackage``. The
+``Post`` class includes the ``DocumentModel`` trait and defines
+properties including ``$primaryKey`` and ``$keyType``:

+.. literalinclude:: /includes/eloquent-models/PlanetThirdParty.php

+   :emphasize-lines: 10,13-14
+   :dedent:
+
+After defining your class, you can perform MongoDB operations as usual.
