The existing documentation is in need of updating, if you would like to re do it that would be great.
I think when I originally created it back around 2005 I created an image because I had trouble using whatever editor I was using back then. It would be easier today with CKeditor using the paste as plain text toolbar to paste in the example tags. TinyMCE would make a mess of it because it wraps every line of what you paste in a paragraph. So we can get rid of that old image.
