Take care on Blue and Red you nead it for a good start ! on the begin buy 5 red potions and use one for the red buff and one for the blue when you are finish take care to all (your) Jungle. When you are Lv 6 recal buy some boots and some stuff fore life steal and start the gank to all the lanes , you must wait for your ultimate and gank with it its the only save way to kill an Enemy Champion Easely.

Thats the easyist begin with Warwick , You Take Money a lot of Kills and you are not dieing so easy

Later if you have Ravenous Hydra or Tiamat you are the lane saver .You can go to every Lane and push them a bit but dont forget to jungle !
