This is a standard ZIP file. The documentation for this helper is contained in a series of videos that are also on this site. Be sure to view the Helper Intro video as well as the three Race Videos. Once you are familiar with the helper, and if you like how it works, and like how the game plays, then you will probably want to create your own "Race Cards" for use with the helper. There are also two videos available that will show you how to do this.
