Brining a Turkey

I have never brined a turkey before. I'm cooking the turkey this year for my group of friends. I was told I have to brine it. I looked it up and it basically just sits in water for several hours before you cook it. I hear it's going to be extremely moist. I hope I don't mess it up. I'm excited to try this different turkey but I'm more excited to only have 2 days with the kids this week!
