How to play 2 Star No Touch, Star Battle 10x10, Easy

This addictive game is a visual version of Sudoku. There can only be 2 stars in each row, 2 stars in each column, and 2 stars in each shape. Below is the link to the puzzle I am playing. Once you learn how to play these, you can't stop! Thanks to Krazy Dad. He is the creator of this puzzle as it appears in the New York Times. This is a fairly easy puzzle that helps you learn some of the tricks so you can advance to some that are much more difficult.
