To add a new course, click on the “Add Course” (1) button in the Courses section.

Another way to add a new course is to import an already exported one. You can do this clicking the caret next to the add course button (2).

For more information about importing/exporting a course check out this article.
Note: whenimporting a Blended, already exported course, the import will not include training sessions. The exported course does not include training sessions, it includes Lessons, Events, Units, and contents but no sessions.
Once you click to add a new course you will be redirected to the add a new course page.

To add a new course fill in all the information and details for the new course, defining its properties one by one. Some properties are required, while others are not mandatory. The required fields are the Name (3) and the Category (4) of the course.
The default course type is set to eLearning (5), for a typical eLearning course based on asynchronous (i.e. at the student’s discretion) access to the course material. If you want to create an instructor-led classroom-based course, change this option to Blended Learning.
There’s also the option to add a short description of the course (6).
If you’re OK with the settings, you can create the course by clicking the ‘Submit’ button. There are also several advanced options that you can see and set by clicking on the ‘Show Advanced Settings’ (7) link.

The advanced settings include: a course code (a short alphanumeric code for easy reference, e.g. ‘CS101’) , language (to inform the users of the course’s language) , a base price (for selling the course), a number of properties such as the status of the course (active or inactive), its visibility on the main catalog etc , availability (Available for which means how many days an enrolled user has access to the course).
Available from/until which indicates from when until when this course is available to enrolled users), CEUs (how many continuing education units the course corresponds to), Depends on (if this course depends on any other courses in the system) and, finally, the certification awarded for completing the course.
Note: you can also have custom fields when you add a Course, which you can create in the Extend Profile section.
When done, click Add.
