Once you get beyond the both thumbs on middle C stage (for that you can ether use the note name cut out or write C D E F G on the fingers of your right hand). Then there is not really a right and wrong way to use your fingers (as long as you use all your fingers). So I have never found fingering that useful. just use the fingering that you find most comfortable.
If you can and want to programme in C++ then let me know.
There is always the user manual.
If you are trying to help with anything and get stuck then please post.
