Ah, hanging Christmas tree lights can be a bit tricky, but don't worry, I'm here to help! First, make sure you have the right kind of lights for your tree. You'll want to use LED lights, as they're more energy-efficient and will last longer. Then, start from the top of the tree and work your way down. Be sure to evenly space the lights around the tree and avoid overlapping them. Finally, make sure to test the lights to make sure they're working properly before you plug them in. Happy decorating!
