Hi @BhupendraSa361 Welcome to the instructor community! You can create your course in the language you want! However, some instructors believe it's better to start with the course using your mother language, if your first course succeeds you can start creating a second course in a second language. You can use the search filter to see how many courses in Hindi already exist here and you can use the Marketplace Insight tool to see how many courses of your topic exist too here.
I hope this helps!
