-### Potential Gotcha
-
-If you have an existing model that you're now making Sortable, existing
-rows won't have an "order" attribute. Django-admin-sortable depends on
-being able to leverage an aggregate Max to determine if a model is sortable.
-
-A good rule of thumb if you're adding django-admin-sortable to an existing
-project is to create a Data Migration using South to set the "order" column
-according to your needs.
-
-For example, if you have a `SortableForeignKey` field, you would need to set
-the "order" column relative to that field, instead of setting the "order"
-column in linear succession.

 ### Rationale
 Other projects have added drag-and-drop ordering to the ChangeList
 view, however this introduces a couple of problems...
