I was just watching a new (at least to me) woodworking show called 'Woodsmith Shop." They just did a segment on various types of joinery. One segment showed how to use a pocket hole jig. I'm pretty sure it's the Kreg jig, but they never said the brand name.
Here is the segment:

I've not used a Kreg jig yet but heard good things about it. This segment really convinced me.
