=head1 NAME
which brings this class together with automatic Serialization of requests
and responses.
-When you use this module, the request class will be changed to
-L<Catalyst::Request::REST>.
+When you use this module, it adds the L<Catalyst::TraitFor::Request::REST>
+role to your request class.

=head1 SEE ALSO
-You likely want to look at L<Catalyst::Controller::REST>, which implements
-a sensible set of defaults for a controller doing REST.
+You likely want to look at L<Catalyst::Controller::REST>, which implements a

+This class automatically adds the L<Catalyst::TraitFor::Request::REST> role to
+your request class. If you're writing a web application which provides RESTful
+responses and still needs to accommodate web browsers, you may prefer to use
+L<Catalyst::TraitFor::Request::REST::ForBrowsers> instead.
