 			<p>Thanks for your interest in PatchAnim.</p>
-			<p>This tool generates a series of bitmaps that are color blends calculated from bezier surface patch values, where
-			   the z coordinate of the patch corresponds to the color intensity that is rendered at that u,v parameter. 
-			   There are three patches available to tailor, one for red, green and blue. These three patches are 
-			   combined into one blend. A series of these patches can be created, and then the software creates a tween 
-			   between them to get a nicely continuous animated blend.</p>

+			<p>This tool creates a sequence of color blends using 
+			<a href="http://en.wikipedia.org/wiki/B%C3%A9zier_surface">Bezier Patches</a>. This sequence of blends is tweened and 
+			animated giving smooth transitions from one blend to another. Blend animations can be outputted to animated gifs, mpegs 
+			or a series of bitmaps.</p>
 
 			<p>A Cubic Bezier <b>curve</b> is a curve defined by 4 control points. The curve goes thru both end points, and
 			the curve is influenced by the two middle points. In fact the slope of the curve at the first point is equal to

 			are mapped to full color (in this case red). In the color blend samples, then, you can imagine that 
 			you are looking straight down on the patch from above. In this application, you can only move the control points
 			in the z direction (into the screen or out of the screen), the x and y positions are fixed.</p>
+
+			<p>To accomplish creating the desired effect, three such patches are available, one for red, green and blue 
+			respectively. Each patch only controls one primary color, and then the values from each patch is put together
+			to generate one full color blend. Since the description of the blend is very succinct (just 16 points), It is 
+			very easy to generate in-between images from two separate blend description.</p>
