 In this example, we will develop an AJAX CRUD (Create Read Update Delete)

 people use JSON instead of XML. The idea is to make something that's closer to
 a GUI app rather than a traditional web page.

-As you can see, the Catalyst framework is well suited for making AJAX
-interfaces, and jQuery is awesome.
+The Catalyst framework with components such as L<Catalyst::Controller::REST> or
+L<Catalyst::View::JSON> is well suited for making AJAX interfaces, as I hope
+we've demonstrated.
 
+From the Catalyst side, it's just a matter of serving and receiving JSON (or
+XML) data or serving HTML fragments, preferrably from a well designed URI API
+based on REST.
+
+Here we used tools for the jQuery JavaScript framework, but other frameworks
+work just as well, such as ExtJS, Dojo, YUI, Mootools, etc.. You can also use
+the jQuery selector functionality in combination with these other frameworks,
+with C<jQuery.noConflict> mode if they override C<$>.
+
+There are also higher-level tools such as L<Catalyst::Controller::DBIC::API> to
+automate accessing your L<DBIx::Class> schema from JavaScript, and even
+L<Catalyst::Plugin::AutoCRUD> which auto-generates a complete AJAX CRUD
+interface to your L<DBIx::Class> schema using ExtJS.
