This thing is dirt-simple. Put the files onto your web site. Run the demo to see how it works. Customize to your own needs as necessary.
OPTIONAL: Install the included VTM file into ColdFusion Studio to enable convenient Tag Insight functionality.
Copy the file cf_pagemonger.VTM to
c:\Program Files\Allaire\ColdFusion Studio 4.5\Extensions\TagDefsCFML
Note that this is the default installation path to Studio v4.5. Your own machine's path may differ depending on how you installed the application.
If ColdFusion Studio is open, close it. When you reopen the program Tag Insight will function.
