 If the field is used to represent a to-many relationship, you should add the `many=True` flag to the serializer field.
 
-Note that nested relationships are currently read-only.  For read-write relationships, you should use a flat relational style.

 ## Example

-**Note**: Nested serializers are only suitable for read-only representations, as there are cases where they would have ambiguous or non-obvious behavior if used when updating instances.  For read-write representations you should always use a flat representation, by using one of the `RelatedField` subclasses.
+Validation of nested objects will work the same as before.  Errors with nested objects will be nested under the field name of the nested object.

 The `depth` option should be set to an integer value that indicates the depth of relationships that should be traversed before reverting to a flat representation.
 
+If you want to customize the way the serialization is done (e.g. using `allow_add_remove`) you'll need to define the field yourself.

 ## Specifying which fields should be read-only 
 
 You may wish to specify multiple fields as read-only.  Instead of adding each field explicitly with the `read_only=True` attribute, you may use the `read_only_fields` Meta option, like so:
