ill give you some steps.
chop down some wood from trees, these produce (wood by itself) 4 wooden planks
after that make a crafting table (i believe its 8 wooden planks on all the outter edges and not one in the middle correct me if im wrong)
with leftover wooden planks use them to make sticks (1 wood plank = 4 sticks) leave at least 3 wood planks to make your first pick or axe
insert 2 wood sticks in the middle bot and middle middle THEN insert wooden planks along the TOP row to make a pickaxe
OR insert 2 wood sticks in middle bot, middle middle then insert wooden planks on the top middle, left top, left middle to make a axe
after you have your wood, you can continue to upgrade to other pickaxes or axes, i would make a pickaxe first (use wooden pickaxe on cobblestone to make stone pickaxes, stone pickaxes on iron to make iron pickaxes etc etc)
hope this helps,
