How do you put a 3 point tactical sling on a G36C?

I have an airsoft WE G39C and it comes with a rear sling hole and an anterior sling hole. I just recently bought a Matrix 3 point Tactical sling in ACU for my JG M4 S-System and im wondering if there are any techniques that will allow me to carry the sling over to the G39. Any tutorials or explanation would be helpful. Thanks!
