What are some optimal Amumu jungle paths?

I always play support, but it's time for me to branch out. I've always wanted to learn jungle so I'm a super noob to jungleing. Before I dive into a practice draft match, I want to practice paths in training so that I kinda know what I'm doing.

I've watched some videos on youtube, but I wanted to get some suggestions here too.

I've heard Amumu should start Red --> Raptors --> Smite @ Blue --> Skuttle/Gank --> enemy raptors --> gromp --> wolves --> raptors/golems --> Back.

If this is the case, do I continue to follow this path throughout the game? Any help for a noob like me is greatly appreciated. Thanks in advance !
