When you click on "create a new course" on the dashboard, you'll be taken to a page where you can enter some basic details about your course and start adding lessons.
Giving your course a name is pretty obvious. Choose something that is short and concise. Consider adding words like for beginners, advanced or Fall 2013 in the title to describe your course more accurately.
Just a few sentences will do! This short description is used in a couple places including the widget (if you use one) and your profile.
Use this toggle to open and close enrollment in your course. By default, enrollment will remain closed until you open it up. When enrollment is closed, the course won't be listed on your profile and nobody will be able to purchase it.
A cover photo helps participants recognize your course. You can use a photo, a collage, or design your own logo. Don't forget to include the title! The cover photo will be shown on the sidebar of your course at all times. It's also used on your course's landing page. That's the page where people will purchase your course.
The tabs on the left hand side will take you to the rest of the course editing options. The options are divided into the sections Edit, Promote and Manage. If you don't know where to start, just go through them in order.
