+## ManyToManyFields with a Through Model
+
+By default, relational fields that target a ``ManyToManyField`` with a
+``through`` model specified are set to read-only.
+
+If you exlicitly specify a relational field pointing to a
+``ManyToManyField`` with a through model, be sure to set ``read_only``
+to ``True``.
+
 ## Advanced Hyperlinked fields
 
 If you have very specific requirements for the style of your hyperlinked relationships you can override `HyperlinkedRelatedField`.
