A pocket hole is simply a hole drilled at an angle that forms a "pocket" for the screw to sit into. You can usually find examples of pocket hole joinery around the house, turn a timber chair upside down or look under a table. After the pocket hole is drilled, a specially designed fastener is used to assemble the joints.
Two Steps:
First, drill the pocket hole. A special step drill bit not only drills the pocket hole, but it also drills the guide hole for the screw in one quick motion. Simply clamp the pocket hole jig securely to your wood, and drill the hole.
The second step is to align the pieces to be joined, temporarily clamp to hold in position, and then drive the screws. A variety of specialized clamps for assembling pocket holes are available.
Above: This is my first attempt, I suspect they'll be a few more. It uses a window winder to provide the clamping force. For the pocket hole guide I'm using a 3/8" Dynabolt sleeve pressed into the angled drill hole, without some sort of sleeve like this the hole would soon become enlarged and out of alignment. Looking at the test work piece the two on the right were drilled freehand, the three on the left is the first attempt using the jig setup as pictured - not bad.
