Zeus pocket question

[jrl5549]

I bought the Zeagle Zeus Zena add on pocket but can not figure out how to attach it. Most of the time I am pretty good at building IKEA furniture and puzzles, it arrived with no instructions and am corn fused, my friends will tell you it is not hard.

I have a Zena and my add on pocket simply velcros over one of the straps.
