What are the details of the Thai cave rescue?

It is good to hear that everyone was rescued, though one of the people involved in the rescue died.

The articles I have seen about this are rather sketchy. Did they have any food? Two weeks is a long time to go without eating. Did the early rescuers bring any food for those remaining? I assume they drank water from their surroundings. How were the people rescued? Did someone dive to their area with scuba tanks, and were then followed to the exit? Why couldn’t everyone be rescued at once?
