Welcome to TE, Hipmama! Are you saying your bike is coming with clipless pedals already? If that's the case, you will need to find out what kind of pedals they are and purchase cycling shoes and cleats for the bottom of your shoes that match the pedals.
For example, if there are SPD pedals on your bike, you'll need SPD cleats on your shoes. I'm no expert, but I started riding my road bike with mountain bike shoes and SPD pedals/cleats.
Whatever you do, the pedals on the bike and the cleats on the shoes have to match.
