How to use AoB (Array of Bytes) Scan in Cheat Engine (in detail)

This tutorial explains, in detail, on how to use Array of Bytes (AoB) scan feature in the famous Cheat Engine. I didn&find any good tutorials so i decided to do it myself. I have explained what is AoB, how and why it works. It&useful for games that have no static memory addresses or are designed to mess up game trainers and so that it is harder to write a trainer for the game, but AoB scan beats it with ease.
