[The CEE]

After briefly skimming the rules, it looks like you have created a very simple and entertaining RPG system. I'm eager to test it out but I was left with one question. Unless I overlooked a section of the rules, how do I know when and the amount of experience to give to my heroes? I'm assuming defeating enemies in combat will grant them experience, but are there any other actions that grant it as well? And when a hero does kill a foe, how much experience does he receive? If I simply missed this section in the rules please forgive my ignorance.
