At the start of the game always sit in the fountain untill the timer starts going up, then around 15 seconds summon treants if your junhling at the beggining. get your mana back and then go to the camps. What i do is use the treants to kill the medium camp while i stack the hard camp. and just continue to farm the jungle for the midas.
When you have your boots and midas. its time to go out into the world and start taking towers sneaky and farming lanes.
Have fun.
