+Organizing models in a package
+==============================
+
+The :djadmin:`manage.py startapp <startapp>` command creates an application
+structure that includes a ``models.py`` file. If you have many models,
+organizing them in separate files may be useful.
+
+To do so, create a ``models`` package. Remove ``models.py`` and create a
+``myapp/models/`` directory with an ``__init__.py`` file and the files to
+store your models. You must import the models in the ``__init__.py`` file.
+
+For example, if you had ``organic.py`` and ``synthetic.py`` in the ``models``
+directory:
+
+.. snippet::
+    :filename: myapp/models/__init__.py
+
+    from .organic import Person
+    from .synthetic import Robot
+
+Explicitly importing each model rather than using ``from .models import *``
+has the advantages of not cluttering the namespace, making code more readable,
+and keeping code analysis tools useful.
