Ad sharing plugin is not working with my theme

My website is ExpressGigs.com. I would like the Ad sharing plugin to work but it doesn't seem to fit my theme. There is very short instructions on it and no way to use it for what it say it is. how does it connects to the original banner ad placements on the site? How do they pay me the percentage of ad revenue? Where would users put their adsense code? It is only a one page set up from the advertising section in the setting section and it doesn't have a front end for users.
