Pick critical runes for early dmg and lunge on lvl 1 so you can easily jump to enemy. At lvl 2 pick burst of speed and now you can easily jump to enenmy and deal a lot of crits with burst of speed you also have some life steal at the begining it will make you more sustainable. When you have to run away from fight use lunge to minion and flash remember that you have heal When you reach lvl 6 you will have your ultimate now and probably boots if you run into a teamfight try to use your ultimate when there is alot of enemy champions nearby(Remember when you ultimate is active no one can hit you :D). When ultimate ends try to hit some people with burst of speed and then lunge away in late game do the same and use Riposte when running away :D. Try to farm as much minions as you can early game

Tell me if you found any mistakes
