Hello! 

To install the presets simply take the content of the Presets folder and put it in

- macOS: /Users/Shared/Eftilo/Stambecco/
- Windows: C:\Users\Public\Documents\Eftilo\Stambecco\

If the mentioned folder doesn’t exist on your machine, please create it manually or launch the full version of Stambecco once; the plugin will then take care of it.

Ciao!
