That being said u can follow 2 paths:

1st scenario: you are playing a normal game or a low elo Q match.
Start with Wolves, move to Blue (u can even do it without help, but your team should give u a hand on this1), then move to Wraiths camp and go to your Red. (Your smite should be ready when u are about to finish this1 ..BUT.. dont worry it wont be necesary for u to finish it). Right after this go straight to enemy red, heal up on the way with your at least 2 pots left and wait on the bushes. 90% of the times u will find the enemy jungler really low on health finishing his red and thats when u get the 1st blood and granting a free-of-gank long lane phase for your team. Meanwhile the enemy team chat will be full of flaming. U just try


2nd scenario: you are playing vs a decent skilled team.
Start with Wolves, move to Blue (Your team should help) then go straight to his red and wait in the bushes until enemy jungler arrives, keep waiting for him to have it almost done, at this moment he is low on health, then ... say: HI!?. Dont use smite to steal it, let the monster fight at your side, anyway the enemy jungler should die pretty fast.
Also keep an eye on your minimap and be sure to ping your team mates on top and mid to come and aid u couse the enemy will try to have your head, and they will, if u and your team are not quick enough to get you tha hell outa there.

Facts
Tips.
. Try to gank as much as possible and remember that a successful gank doesnt always end with a kill, if u make them waste Flash or even if u just released the pressure on the lane, then u succeded. Ofcourse it would be great to grab a kill so aim for it just dont try too hard and dont overextend chasing.

. If u see the enemy jungler trying to gank top be sure to ping the area for your top laner to be aware and if u know he/she will be alright head straight to enemy blue area and clean it for him always leaving 1 of the lesser monsters alive... just so he knows ;) ..and also to prevent the respawn, denying level to your enemy jungler = GG

. Try do the dragon as fast as posible and all the times u can. It represents experience and 190 G for your team

. WARDS are your best friends so as a jungler u should keep a ward on the enemy buffs and if u realize your jungle is being farmed then u should ward your buffs too, they are very important early, mid and late game so keep an eye on them.
