 attribute) but has no C<:CaptureArgs> attribute is treated by Catalyst
 as a chain end.
 
+Allowed values for CaptureArgs is a single integer (CaptureArgs(2), meaning two
+allowed) or you can declare a L<Moose>, L<MooseX::Types> or L<Type::Tiny>
+named constraint such as CaptureArgs(Int,Str) would require two args with
+the first being a Integer and the second a string.  You may declare your own
+custom type constraints and import them into the controller namespace:

+    package MyApp::Controller::Root;
+
+    use Moose;
+    use MooseX::MethodAttributes;
+    use MyApp::Types qw/Int/;
