Click on the cheat sheet abovw for the gear selection order, the rune page build, and the summoner abillites to use.
The first one is for Jungleing, and the second is for laneing. You will notice summoner Heal for the jungleing guied. This is used for the start and to lvl 6. I like useing this because using it alows you to jungle longer because you don't have any mana you need to regen, only health. Also if you go for blue or red buff first, it helps greatly so you know you won't die. If you are confident you can jungle with out useing it then don't, and go with another spell that can help you, like ignite. In the laneing guide you will see ghost. If you don't like useing ghost you can easily replace it with Flash or another escape/utility spell. In both of the guides, gear towards the end is harder to decide befor the game starts then in the begining. Towards the end I would suggest using a defense item or armor pen.
Lee sin is an amazing champion, and with some practice you will be able to destroy your enemys.
