To get started with your Course Guide you need to add a new Course. You can add as many courses as you want to.
When you add a new course you can add a description to the course - this is a nice feature for new Golfers who has not tried your course yet. You can also add tee distance, HCP and par to every hole on the course.
This is also where you have an overview of all the holes in your course. By pressing one of the holes you are able to make some Pro Guidelines that specially new Golfers find helpful.
You can add a new course by pressing Courses → + New
