"Debugger Helpers" documentation not adequtae

The documentation here seems, shall we say, lacking. It's as if it describes all the constituent parts of a car: valves, hoses, bolts, tubes, etc, but fails to describe how to put it together.

I've googled a lot and tried many different things. I can't for the life of me even get my script to run, much less have it show something interesting in the debugger.

Would someone, who knows what they're doing, on BOTH mac and windows, please illuminate this for us all? Pretty please?
