You ask, I deliver (sort of): The shortest Ajax+Catalyst tutorial in
the world — http://sedition.com/a/2670

That is minimalistic but it does work and gives a jumping
off place. Much easier to hack from a working piece than
getting frustrated trying to make a thing work.

The only thing needed to set up jQuery is shown in the XHTML
template in the examples. Here's a short version; Google hosts
it and you just wrap it in the document ready function like so-

<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/ 
jquery.js"
   type="text/javascript"></script>
<script type="text/javascript">//<![CDATA[
jQuery(function($) {
   // your jQuery code goes here!
});
//]]> </script>
</head>

Once you have this running, hit the docs. They'll make more sense
after you follow through this simplistic example.

Have fun!
