Elise build?

Finally after nolyfed for a stright week just to get 6300 points i wanna buy Elise cause she seems alot of fun and is considered as one of the top Junglers and since Jungle role is my least played role i wanna learn to play it but all i know about elise is that it seems most effective build is to build her like bruiser? if so how do you exactly build her?
