to make it smooth to upgrade to L<Moose> when you need more than minimal
features.
+=head1 Moo and Moose - NEW, EXPERIMENTAL
+
+If L<Moo> detects L<Moose> being loaded, it will automatically register
+metaclasses for your L<Moo> and L<Moo::Role> packages, so you should be able
+to use them in L<Moose> code without it ever realising you aren't using
+L<Moose> everywhere.
+
+Extending a L<Moose> class or consuming a L<Moose::Role> should also work.
+
+This means that there is no need for anything like L<Any::Moose> for Moo
+code - Moo and Moose code should simply interoperate without problem.
+
+However, these features are new as of 0.91.0 (0.091000) so while serviceable,
+they are absolutely certain to not be 100% yet; please do report bugs.
+
+If you need to disable the metaclass creation, add:
+
+ no Moo::sification;
+
+to your code before Moose is loaded, but bear in mind that this switch is
+currently global and turns the mechanism off entirely, so don't put this
+in library code, only in a top level script as a temporary measure while
+you send a bug report.
