+Overriding methods on an ``InlineFormSet``
+------------------------------------------
 
-See :ref:`model-formsets-overriding-clean`, but subclass
+When overriding methods on ``InlineFormSet``, you should subclass
 :class:`~models.BaseInlineFormSet` rather than
 :class:`~models.BaseModelFormSet`.
 
+For example, If you want to override ``clean()``::
+
+    from django.forms.models import BaseInlineFormSet
+
+    class MyModelFormSet(BaseInlineFormSet):
+        def clean(self):
+            super(MyModelFormSet, self).clean()
+            # example custom validation across forms in the formset:
+            for form in self.forms:
+                # your custom formset validation
+                ...
+
+See also :ref:`model-formsets-overriding-clean`.
+
+Then when you create your inline formset, pass in the optional argument
+``formset``::
+
+    >>> from django.forms.models import inlineformset_factory
+    >>> BookFormSet = inlineformset_factory(Author, Book, formset=MyModelFormSet)
+    >>> author = Author.objects.get(name=u'Mike Royko')
+    >>> formset = BookFormSet(instance=author)
