How do I use an airsoft sling?

I have a JG G36C and i just can't figure out where and how to put on the sling. I can attatch it on the gun through many holes but i can't figure out what position to wear the sling at. It's so confusing! It's just a standard sling that you usually get with AEG's. So i'm just wondering how you guys do it? Maybe attatch a video? Thanks! :)
