 What's new in Django 1.11
 =========================
 
+Class-based model indexes
+-------------------------
+
+The new :mod:`django.db.models.indexes` module contains classes which ease
+creating database indexes. Indexes are added to models using the
+:attr:`Meta.indexes <django.db.models.Options.indexes>` option.
+
+The :class:`~django.db.models.Index` class creates a b-tree index, as if you
+used :attr:`~django.db.models.Field.db_index` on the model field or
+:attr:`~django.db.models.Options.index_together` on the model ``Meta`` class.
+It can be subclassed to support different index types, such as
+:class:`~django.contrib.postgres.indexes.GinIndex`. It also allows defining the
+order (ASC/DESC) for the columns of the index.
