You will have to use the built-in Help menus in order to learn how to properly save the presets and the patches. However, I've searched the web, but I couldn't find a proper manual file and the official website doesn't provide anything about it, therefore searching through the installation folder and in the Help section is the best bet to obtain something you can use.
I also recommend watching the tutorials posted on YouTube and various websites where users work with this application. You might learn from there how it's done it.
