What is the story about Artemis' birth?

Artemis was the daughter of Zeus and Leto. When Hera, the wife of Zeus, found out that Leto was pregnant with twins fathered by Zeus, she flew into a jealous rage and forbade all lands and waters to give Leto rest. Poor Leto had to wander the earth to find a place to give birth. She finally came upon the floating island of Delos. Since it was floating, it was neither land or water and was free from Hera's curse. There Leto gave birth to Artemis and her twin brother Apollo. Artemis was born first and became her mother's midwife.
