Hi @Abdelhadi2021 Since we function primarily as an on-demand, video-based platform, you’ll need to upload your video files directly to Udemy. In other words, students must be able to view your course lectures on the Udemy platform. You can start creating your course via this link. To add a new lecture to a course please follow the steps that are outlined in this support article.
Also, this page is full of information about teaching on Udemy.
