Here you go man... this is a decent video showing the footwork and a text version showing the steps.
Double-Clutch
Once you get good at this, then try heel-toe, don't bother now. This will improve your shifting speed and give you the basics that you need to know to make heel-toe down shifting easier.
The steps for double-clutching are actually quite easy... being good at it just comes with practice. Don't give up; nobody does it perfectly at first. You learn something about your car, about weight transfer and how that translates to a smoother and ultimately faster ride... on top of it, you don't rely on a fallible electronic component to do the work for you.
