Learn to make and mix shaders in Daz Studio 4.8 or higher

I want to learn how to create my own shaders as well mix them..

I have found the shader tutorial i that i bought  from daz very simple and not very clear as to how to do this..

i have also  looked the you tube tutoria by Carmine as to make this but i found it confusing...

So i would like to ask those who have managed to make shaders for some help and guidance in this matter please

Thanks in Advance
