+Model Form Functions
+====================
+
+.. module:: django.forms.models
+   :synopsis: Django's functions for building model forms and formsets.
+
+.. method:: modelform_factory(model, form=ModelForm, fields=None, exclude=None, formfield_callback=None,  widgets=None)
+
+    Returns a :class:`~django.forms.ModelForm` class for the given ``model``.
+    You can optionally pass a ``form`` argument to use as a starting point for
+    constructing the ``ModelForm``.
+
+    ``fields`` is an optional list of field names. If provided, only the named
+    fields will be included in the returned fields.
+
+    ``exclude`` is an optional list of field names. If provided, the named
+    fields will be excluded from the returned fields, even if they are listed
+    in the ``fields`` argument.
+
+    ``widgets`` is a dictionary of model field names mapped to a widget.
+
+    ``formfield_callback`` is a callable that takes a model field and returns
+    a form field.
+
+    See :ref:`modelforms-factory` for example usage.
+
+.. method:: modelformset_factory(model, form=ModelForm, formfield_callback=None, formset=BaseModelFormSet, extra=1, can_delete=False, can_order=False, max_num=None, fields=None, exclude=None)
+
+    Returns a ``FormSet`` class for the given ``model`` class.
+
+    Arguments ``model``, ``form``, ``fields``, ``exclude``, and
+    ``formfield_callback`` are all passed through to
+    :meth:`~django.forms.models.modelform_factory`.
+
+    Arguments ``formset``, ``extra``, ``max_num``, ``can_order``, and
+    ``can_delete`` are passed through to ``formset_factory``. See
+    :ref:`formsets` for details.
+
+    See :ref:`model-formsets` for example usage.
