+Programmatically creating permissions
+-------------------------------------
+
+While custom permissions can be defined within a model's ``Meta`` class, you
+can also create permissions directly. For example, you can create the
+``can_publish`` permission for a ``BlogPost`` model in ``myapp``::
+
+    from django.contrib.auth.models import Group, Permission
+    from django.contrib.contenttypes.models import ContentType
+
+    content_type = ContentType.objects.get(app_label='myapp', model='BlogPost')
+    permission = Permission.objects.create(codename='can_publish',
+                                           name='Can Publish Posts',
+                                           content_type=content_type)
+
+The permission can then be assigned to a
+:class:`~django.contrib.auth.models.User` via its ``user_permissions``
+attribute or to a :class:`~django.contrib.auth.models.Group` via its
+``permissions`` attribute.
