What kind of supercharger for 5.7 hemi?

I have a stock 2007 Dodge Charger R/T and would like to add a supercharger onto it. I don't reallly know a whole lot about what i would need other than a supercharger lol. So my question is what else would i need to add to the vehicle other than a supercharger? I hear upgrading fuel injectors is a must as well. What kind of superchargers are you guys running? and what else would i need other than a supercharger? As of right now the vehicle is 100 percent stock. Any help would be greatly appreciated!
