Golite Shangri-La 3 – How to Hang It from A Branch

Hi

I would really appriciate assistance on how one realistically goes about using the Shangri-La 3 by hanging it from a branch. I'm a complete novice to this, so I could only guess that a certain type of knot that would give adjustment would be preferable. Also is it better to try and pitch between 2 trees or pitch under an overhang.

Thanks in advance.
