+======================
+Barbican Sample Policy
+======================
+
+The following is a sample Barbican policy file that has been auto-generated
+from default policy values in code. If you're using the default policies, then
+the maintenance of this file is not necessary, and it should not be copied into
+a deployment. Doing so will result in duplicate policy definitions. It is here
+to help explain which policy operations protect specific Barbican APIs, but it
+is not suggested to copy and paste into a deployment unless you're planning on
+providing a different policy for an operation that is not the default.
+
+The sample policy file can also be viewed in `file form <_static/barbican.policy.yaml.sample>`_.
