The first thing you want to do in every round is buy a items at the shop. Their are suggested items for each character so start with that first. As you get better you may want to buy different starting items then the recommended ones but I'll leave that for a later guide.

While in your lane you first want to go for minion kills. Any time the enemy players get in range you should attack them with your attacks and skills. Be careful about ganks coming from the other lanes. Ganks are when enemy players come to your lane with intent to kill you. If you take your enemy's turret in your lane you are free to roam around the map to go and gank other players.

The game is won when your or the enemy team kill the nexus. The nexus is the big gem object near the beginning of the map. Make sure to protect the nexus at all costs!
