Early jungling is easy with Shaco. Always start your Jack In The Box, the creepy boxes. Start your blue or red buff, you wont need a leash. Place your Jack In The Box down constantly when the timer hits 0:44. You should have several boxes down by 1:40 and you will take almost 0 damage from your buff by the time it is dead. Immediately run over to enemy jungle and steal their buff or try and kill them. Also ganks at level 2 and 3 work very well for shaco.

Always watch for your buff timers. Any jungler knows that. It's important to watch for buff timers in enemy jungle as well. You need to steal their buffs AS MUCH AS POSSIBLE. By this time you should have a good amount of damage so don't forget to gank. Don't be afraid to enter enemy jungle either, you have on of the best escapes on the game and putting them behind in crucial.

At level 6 or 7 you should be able to solo dragon and depending on how much damage you have, should be able to solo rift herald . In order to do so place your Jack In The Box and use your Hallucinate. The Dragon will focus your boxes and then you, have it switch between your clone and you for the best damage. When your clone blows up it does a good amount of damage but you need it to tank as well.

There are several ways to gank. You can:
1) Start with Deceive, come in invisible and get behind them to hit them with an auto then Two-Shiv Poison, auto, Ignite.

2) Run into lane and use your Deceive as an escape.

3) Use your Hallucinate and send your clone in first and you approach with your Deceive.

Just remember, your Hallucinate lets you dodge Abilities and Skill shots so use when necessary
