Correct file permissions for WordPress

I've had a look over [here][1] but didn't find any details on the best file permissions. I also took a look at some of WordPress's form's questions over [here too][2] but anybody that suggests 777 obviously needs a little lesson in security. In short my question is this. What permissions should I have for the following: 1. root folder storing all the WordPress content 2. wp-admin 3. wp-content 4. wp-includes and then all the files in each of those folders?
