Chest Freezers

My dad is giving me a chest freezer. It was given to him by a friend who didn't need it anymore, and he already has one so he is passing it to me. I am very excited as I enjoy bulk cooking, shopping, etc. to save time, money, waste, etc. I do think it to be imperative to formulate some sort of syystem/worksheet or something in order to keep up with what's in there, ane how long it has been there. Any suggestions or methods you have found effective?
