Driving school is not required but not a bad idea to learn from an expert on how to drive with a manual transmission. But, if you wanna go the self-taught route, youtube is definitely your friend. There's a BUNCH of video tutorials and written ones to learn about it. It's important to understand the underpinnings of how the engine works in regards to how you drive since you'll have a better understanding of why you would shift gears and other stuff. A little googleing will go a long way.
