To upload a course:
Click Create Content > Upload Course > Create from the Content Management page.
A file dialogue box appears.
Make your selection and click Open.
You are returned to the Content Management page, and if you refresh the page you can see your new course added to the bottom of the page.
Courses must be JSON files with a specific set of attributes. You can download an existing course through the course’s Edit screen and use that course JSON as an example for creating your own custom JSON courses.
Each course has a unique contentId. If you upload a course with the same contentId as a course that is already in Learn for Jira, the course you are uploading will overwrite the course that is already there, without any sort of warning alerts.
