Beginner's Guide to Replace Cartridge on Music Hall MMF 2.2

I have a MMF 2.2 turntable and its stock cartridge started having noise on the left channel. I bought a new cartridge but have never set up a cartridge and turntable before. I also don't have the protractor template that came with the turntable originally. I looked into professional installation but it would cost almost as much as the turntable. Does anyone know where I can find some good resources to help change the cartridge on this particular turntable with no experience?
