Minecraft wiki entry for Superflat_survival, associated text: Using iron that you have found in chests and got from killing zombies, make a bucket. If you don't have enough, go searching more chests for more, or if all else fails, kill more zombies until you have three iron ingots. Go to a village and take water from the well and lava from the smithy to make a cobblestone generator. Now you have a renewable source of wood and cobblestone. Dig for dirt , and smelt logs in a furnace to make charcoal for torches, and you'll have everything you need. Your next step is getting renewable iron.
