Minecraft wiki entry for Superflat_survival, associated text: Put fences around a farm or two, to keep the slimes from trampling it, or make a farm inside of your house. Make a furnace from cobblestone you have gathered, so you can smelt logs into charcoal for torches. Light up the village; you don't want monsters everywhere. Place some torches near your tree farm so that they grow faster (or use bonemeal for a quicker process). Now that you have a renewable source of wood, your next step is cobblestone.
