+=== Derived values ===
+We can create a field which is derived from others (this example will put ''joe.blow@example.com'' in email field):
+<code python>
+class UserFactory(factory.Factory):
+    FACTORY_FOR = models.User
+    first_name = 'Joe'
+    last_name = 'Blow'
+    email = factory.LazyAttribute(lambda a: '{0}.{1}@example.com'.format(a.first_name, a.last_name).lower())
+</code>
+=== Unique values in sequence ===
+We can create a field which is auto-incremented as:
+<code python>
+class UserFactory(factory.Factory):
+    FACTORY_FOR = models.User
+    email = factory.Sequence(lambda n: 'person{0}@example.com'.format(n))
+</code>
+=== Associate factories ===
+We can associate a field with other factory to create other sub instance:
+<code python>
+class PostFactory(factory.Factory):
+    FACTORY_FOR = models.Post
+    author = factory.SubFactory(UserFactory)
