It basically covers how to get food, where to train, and buy armor.
Step 1: Food and where to get it
Step 2: Armor and Weapons
If you have enough money for this, go buy some armor and a weapon. When you're lvl 3 you can only wield up to iron so if you have enough money go buy either an iron longsword or scimitar. then buy yourself a shield, platebody or chainmail, helmet, and some platelegs or a plateskirt (girls).
