Okay, for step one you need to get the command blocks in your inventory. Make sure you have cheats ON and say "/give (player name) command_block". After you get in in your inventory place 5 in a row. Then you right click the first one and put the command "/give @a 306". Then exit out of that command block and right click the next one. In this one you put "/give @a 307", then in the next put 308, then 309. In the last command block put "/give @a 261".
