Hey @PritamVidulkar, welcome to the community! You can start creating your course via this link.
Courses must have at least 30 minutes of video content and at least 5 lectures or learning modules.
In order to ensure that students have great learning experiences, we also have a Quality Review Process that every course goes through. For more information on this please click here.
This section includes extensive resources on how you can create a Udemy course and get started.
Hope this helps!
