+===============================
+
+An **auto allocated topology** allows admins to quickly set up external
+connectivity for end-users. Only one auto allocated topology is allowed per
+project. For more information on how to set up the resources required
+for auto allocated topology review the documentation at:
+http://docs.openstack.org/newton/networking-guide/config-auto-allocation.html

+.. option:: --check-resources
+
+    Validate the requirements for auto allocated topology.
+    Does not return a topology.
+
+.. option:: --project <project>
+
+    Return the auto allocated topology for a given project.
+    Default is current project.

+
+    Domain the project belongs to (name or ID).
