teach me how to jungle?

I'm a plat 1 "dropped from D5" Jungle and I main Ekko/Tahm mainly and am about to start to pick up Hec again and Eve I'm also going to be starting my stream soon if you would want to learn.

I am a jungle main, I play all of them and have been playing them since Season 3 to 4. I am Silver 3 and on a couple teams in silver presently making our way to gold. I don't mind sharing some free advice.
