ELI5: How do superchargers make cars go faster? Or why?

Wondering how and why they work. Mostly why.

Put simplistically, the power from an engine is made from the combustion of fuel and air. A supercharger compresses the incoming air, allowing more to enter the engine. More fuel is added to the engine via the fuel injectors, and the two combined combust to create more power than would have otherwise been made.
