+Neutron API policies and supported roles
+========================================
+
+As part of the ``Consistent and Secure Default RBAC`` community goal [#]_
+Neutron implemented support for various scopes and personas in all of the API
+policies which are defined in the Neutron code.
+
+Roles supported by the default Neutron API policies
+---------------------------------------------------
+
+Roles supported by the default Neutron API policies are:
+
+* PROJECT_READER - this role is intented to have read only access to the
+  project owned resources.
+* PROJECT_MEMBER - this role inherits all of the privileges from the
+  PROJECT_READER role and also has access to ``create``, ``update`` and
+  ``delete`` project owned resources.
+* PROJECT_MANAGER - this role inherits all of the privileges from the
+  PROJECT_MEMBER role and additionally is allowed to do more operations on the
+  project owned resources.
+* ADMIN - this role is the same as it was in the "old" default policies. A user
+  with granted ADMIN role is allowed to do almost every possible modifications
+  on all resources, even those which belong to different projects.
+* SERVICE - this is a special role designed to be used for the service to
+  service communication only (like e.g. between nova and neutron), it doesn't
+  inherit any privileges from any other roles mentioned above.
+
+Default API policies defined in Neutron
+---------------------------------------
+
+By default all of the existing API policies can be used with the ``project``
+scoped tokens only. Tokens with ``service`` scope are not supported by any of
+the policies defined in Neutron code.
+
+Default API policies
+--------------------
+
+Default API policies defined in the Neutron code can be found in the
+:ref:`Policy Reference` document.
