There's plenty of advice out there if you Google it.
Here's Canon's page on it:
Photographing the Moon and Moonlit Landscapes can create dramatic, surreal landscapes that will set your photography apart from the rest.
IME, it's brighter than you think. You're basically photographing (reflected) sunlight. Too dark is better than too bright, if you want to see the craters and all. You can always increase the brightness in post.
You will of course need a tripod. And the longer the focal length the better, if you are only photographing the moon. (The Canon link has a graphic that shows you how big the moon will be in your frame, with different focal lengths.)
If you want to photograph a moonlit landscape, Scott Kelby recommends doing it the day before the moon is full. The moon won't be as bright, so you'll be able to expose the darker landscape better.
