So not user friendly and no literature on how to use it.

Hi,

Hope the following information could help.

The documentation for the plugin is located on the website – educatorplugin.com

Please check the following articles:

1. How Educator Plugin Works
2. Configuring Educator
3. Theming Educator

Also, there are instructions about adding a currency – Adding Support For a Currency

You can also use the search box on the website to search for the keywords that are of interest to you (e.g., currency, theming, etc).
