Not Clear How to Implement Pay Per View Plugin

I just finished installing the Pay Per View plugin inside my site and it's really not clear how I configure / set it up protect my content.

My goal is to be able to use this plugin to sell and then grant access to video based content that will be offered through my site. Ideally my clients will come to the site, find a video that they want, purchase it using the plugin and then have access to it whenever they want inside the site.

I'm not interested in setting up a membership site. I really just want to be able to sell and provide access to videos that customers can buy inside the site. One of the main reasons why I'm interested in the Pay Per View plug-in is because it keeps the customer on your site when they are watching their purchased content.

Do you have a step by step guide or set of instructions that I can review in order to make the setup / integration of this plugin more clear?
