 =====================
 
 The ``modeladmin`` module allows you to add any model in your project to the Wagtail admin.  You can create customisable listing
-pages for a model, including plain Django models, and add navigation elements so that a model can be accessed directly from the Wagtail admin. Simply extend the ``ModelAdmin`` class, override a few attributes to suit your needs, register it with Wagtail using an easy one-line ``modeladmin_register`` method (you can copy and paste from the examples below), and you're good to go. This customisation doesn’t need to extend ``Page`` or be registered as a ``Snippet``, and it won’t interfere with any of the existing admin functionality that Wagtail provides.
