+	  The SELinux Reference Policy project (refpolicy) is a
+	  complete SELinux policy that can be used as the system
+	  policy for a variety of systems and used as the basis
+	  for creating other policies. Reference Policy was originally
+	  based on the NSA example policy, but aims to accomplish
+	  many additional goals.
+
+	  The current refpolicy does not fully support Buildroot
+	  and needs modifications to work with the default system
+	  file layout. These changes should be added as patches to
+	  the refpolicy that modify a single SELinux policy.
+
+	  The refpolicy works for the most part in permissive mode. Only
+	  the basic set of utilities are enabled in the example policy
+	  config and some of the pathing in the policies is not correct.
+	  Individual policies would need to be tweaked to get everything
+	  functioning properly.
