Will someone summarize this for me ! 10 easy points !!!!!!!!!!!?

So they were trying to name a city. Athena and Poseidon both wanted it so they had a contest. Poseidon lets a spring of salt water out of the ground but no one can use it because it is salty. Athena gives them the olive branch and everyone likes it because it is so useful. So they called the city Athens. But Poseidon was not happy so he cursed the place so that their will be a shortage of water.
