I will try to be good and update each week so if you want to follow along you can.
The things that you need is at least 5 boxes, one that should be labeled "Food" and is the only box that gets food in it, so the others aren't cotaminated with the food scent, treats that your dog really loves, and some different areas to work in.
The first week the boxes are all in a line. Before I set L'Ox down to work, show him that I am putting the treats in the treat box then I do a "shell game" with the box, tapping it against the other boxes in the line and usually saying things like, "Where's your treat? Is it in this box? Oh, look at this box it looks so good." etc, and at some point switching the food box with one of the other boxes so that he doesn't just cue into the last box I was at and has to really work to find the treats. We do 3 searches in a training session and our goal for the week is to work in 5 locations. Mine will probably be the kitchen, the living room, the backyard, the school down the street, and at a friend's house.
It makes things much easier if you have someone to help you but you can work by yourself using a tether or baby gate.
