Do anyone know how to use KISSsoft gear design software?

I was looking for a gear design software. And then I found KISSsoft. But I need to figure out is it suitable for me or not. So I am looking for tutorials about it. I found official tutorials but they are too confusing to understand and there are no proper order between videos. Do anyone know tutorials about KISSsoft or do you recommend another gear design software for this noob fella? By the way I am using solidworks if it is important.
