Add new method by functions.php?

Hey guys, thanks for this plugin.

I have recently added PayHub payment gateway to my store but it’s not supported. I wonder if there is a way to add support for new payment method paired with one of existing icons (e.g. pf-credit-card) by adding some extra lines to functions.php in my template folder?

Also I would kindly ask for some tutorial/detailed instructions how to customize this plugin. I’ve read the FAQ but it gives only general instructions – not very useful for someone who’s new to php/wordpress code.

Thanks for reading!
