I'm so confused... Need help

I hit level 30 not too long ago, bought the champion pack, got some runes and actually made real mastery pages. I've had experience in every role, mainly mid and support, except jungle. I've never jungled, and I refuse to play ranked without having an understanding of the role. But Ever since the jungle changed, I haven't been able to find any guides for beginners to jungling. If you guys have any suggestions or tips I would greatly appreciate it. Plus I know I shouldn't have waited this long to learn to jungle, especially since is my favorite champ. TOP AP RAMMUS OP
