=head1 DESCRIPTION
-Role support in Moose is pretty solid at this point. However, the best
-documentation is still the the test suite. It is fairly safe to assume Perl 6
-style behavior and then either refer to the test suite, or ask questions on
-#moose if something doesn't quite do what you expect.
-
-We are planning writing some more documentation in the near future, but nothing
-is ready yet, sorry.
+The concept of roles is documented in L<Moose::Manual::Role>. This document
+serves as API documentation.
