Minecraft wiki entry for Complete_main_adventure, associated text: When first beginning a game of Survival or Hardcore (recommended for true adventure style, and it’s also really hard), collect wood from nearby trees. Wood is needed to create a crafting table and a wooden pickaxe. The wooden pickaxe is necessary to harvest cobblestone, which will allow you to create a stone pickaxe and a minimum of 1 furnace, although 3 are recommended later on. Also useful at the cobblestone level, a stone sword is advised as one needs to upgrade to iron next, and it is likely that will take a while and night will probably come before then, and some degree of protection is advised. After a stone pickaxe is obtained, use it to harvest a minimum of 3 iron ingots and a minimum of 1 coal. It is recommended to harvest 32 iron ingots to create iron armor and an iron sword, along with an iron pickaxe and bucket for water. At this stage, if you want to try to go to the nether and you are having a hard time finding diamonds, you could also gather an additional 6 iron to make 2 buckets, fill one with water, and find a natural lava pool on the surface. Once you have found it, you can place the water and lava next to each other around a backboard to create a frame. Note that you need to have the lava turn into obsidian quickly, because it will flow down and make it harder to fill the frame.
