What does Le Chatelier's principle say happens to an equilibrium when temperature is changed or a catalyst is added?

The temperature moves the equilibrium differently depending on if the forwards reaction is exothermic or endothermic. If its endothermic the equilibrium moves to the right giving more products. The addition of a catalyst will only ever increase the rate of reaction and does not change the equilibrium position.
