+		<p>jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. If you're new to jQuery, you might be interested in the <a href="http://learn.jquery.com/">jQuery Learning Center</a> tutorials.</p>

+		<p>The API docs aren't specifically versioned, but you need to pay attention to the version info on each page.</p>
