Payment gate from GitHub

Hello, I would like to add to my woocommerce store a payment gate from Comgate. They have PHP SDK on GitHub for "simple" instalation, but on the whole internet I can't find some tutorial how to implement it to the WordPress page.
Note – I dont know anything about GitHub yet… Is there someone that can simplify it to me and write some tutorial how to do it?
Thanks a lot ❤️
