+<h1>jQuery SVG Basics</h1>
+<p>This page demonstrates the very basics of the <a href="http://keith-wood.name/svg.html">jQuery SVG plugin</a>.
+	It contains the minimum requirements for using the plugin and
+	can be used as the basis for your own experimentation.</p>
+<p>The page creates an SVG document in the area below and draws an initial display.
+	The buttons then add randomly sized and coloured shapes on demand.</p>
+<p>For more detail see the <a href="http://keith-wood.name/svgRef.html">documentation reference</a> page.</p>
