@ejschulz. Thanks for using my module. It comes with a readme.txt file that explains how to use it basically. You can also have a look at the original webpage with usage instructions.
It seems like you are new to joomla in general. Joomla gives you access control over both pages and module instances. You can also have multiple module instances, and apply them to different pages, or different positions on the page. There are tutorials online to help you with understanding joomla.
Hope this helps.
