How to connect PiGlow?

Hi, my PiGlow just came in the mail. Problem is I don’t know how to attach it to my Pi. I watched some videos and put it in the correct position but it seems to not stay on it. it just tilts down, or if I turn the pi over a little it just falls off. Am I supposed to press really hard to make it stick to the pins?

You will need to push down firmly on the header for it to mate properly with the header on your Pi. It certainly won’t balance on top ;-)
