Everything in a NutshellSTART OF THE GAME:
Try to harass as much as you can with your Q. That will hopefully get them to miss a couple CS and can get you ahead. Don't forget to use your W when you get lvl 2 to help you CS if you are getting harassed since it has some range. Once you get lvl 4 is when you start to do damage. Make sure you E, Q, auto-attack, W. That will do major damage and push your opponent out of lane.
You are going to need to start roaming a bit to get yourself some kills. Push your lane to the tower and go. By this time, you have your R key. When going in on an opponent, make sure you E, W, R, then Q when you can. If you can't get the Q in there, don't worry to much because you will probably get the kill anyways. Repeat this process to help out your teammates and get you fed.
You need to have good positioning late game because they will be looking to DPS you down as fast a possible so this is where ZHONYAS HOURGLASS works the best. When you get into a team fight, you wait for either the top/jungle/support, to engage, E to someone in the middle of them all and just press your R key and watch the kills rack up. If you see your getting low hp fast, use ZHONYAS! And remember when you get a kill or an assist, your abilities had cooldown reducution so look and see if they are up to be used again!
