 Sortable has one field: `order` and adds a default ordering value set to `order`.
 
+#### Model Instance Methods
+Each instance of a sortable model has two convenience methods to get the next or previous instance:
+
+    .get_next()
+    .get_previous()
+
+By default, these methods will respect their order in relation to a `SortableForeignKey` field, if present. Meaning, that given the following data:
+
+| Parent Model 1 |               |
+|----------------|---------------|
+|                | Child Model 1 |
+|                | Child Model 2 |
+| Parent Model 2 |               |
+|                | Child Model 3 |
+|                | Child Model 4 |
+|                | Child Model 5 |
+
+"Child Model 2" `get_next()` would return `None`
+"Child Model 3" `get_previous` would return `None`
+
+If you wish to override this behavior, pass in: `filter_on_sortable_fk=False`:
+
+    your_instance.get_next(filter_on_sortable_fk=False)
+
+You may also pass in additional ORM "extra_filters" as a dictionary, should you need to:
+
+    your_instance.get_next(extra_filters={'title__icontains': 'blue'})

 ### Adding Sortable to an existing model
 If you're adding Sorting to an existing model, it is recommended that you use [django-south](http://south.areacode.com/) to create a schema migration to add the "order" field to your model. You will also need to create a data migration in order to add the appropriate values for the `order` column.
