+Overriding the default field types or widgets
+---------------------------------------------
 
 The default field types, as described in the `Field types`_ table above, are
 sensible defaults. If you have a ``DateField`` in your model, chances are you'd
 want that to be represented as a ``DateField`` in your form. But

+``ModelForm`` gives you the flexibility of changing the form field type and 
+widget for a given model field.
+
+To specify a custom widget for a field, use the ``widgets`` attribute of the
+inner ``Meta`` class. This should be a dictionary mapping field names to widget
+classes or instances.
+
+For example, if you want the a ``CharField`` to be represented by a
+``<textarea>`` instead of its default ``<input type="text">``, you can override
+the field's widget::
+
+    class AuthorForm(ModelForm):
+        class Meta:
+            model = Author
+            fields = ['name', 'title', 'birth_date']
+            widgets = {
+                'name': Textarea(attrs={'cols': 80, 'rows': 20}),
+            }
+
+The ``widgets`` dictionary accepts either widget instances (e.g.,
+``Textarea(...)``) or classes (e.g., ``Textarea``).
+
+If you want to further customize a field -- including its type, label, etc. --
+you can do this by declaratively specifying fields like you would in a regular
+``Form``. Declared fields will override the default ones generated by using the
+``model`` attribute.
 
 For example, if you wanted to use ``MyDateFormField`` for the ``pub_date``
 field, you could do the following::
 
-    >>> class ArticleForm(ModelForm):
-    ...     pub_date = MyDateFormField()
-    ...
-    ...     class Meta:
-    ...         model = Article
+    class ArticleForm(ModelForm):
+        pub_date = MyDateFormField()
+    
+        class Meta:
+            model = Article
 
-If you want to override a field's default widget, then specify the ``widget``
+If you want to override a field's default label, then specify the ``label``
 parameter when declaring the form field::
 
    >>> class ArticleForm(ModelForm):
-   ...     pub_date = DateField(widget=MyDateWidget())
+   ...     pub_date = DateField(label='Publication date')
    ...
    ...     class Meta:
    ...         model = Article
