Hi @SabaMtchedl256,
I hope you are enjoying your weekend 😊.
You can absolutely publish your course, as long as it meets our quality standards. Please check out our Course Quality Checklist here.
Once published, you can add or edit course lectures at any time. Click here to learn more about updating content.
As you mentioned "bonus content" in the title of your post: In case you are referring to the bonus lecture, it's the same as with the other lectures mentioned above.
The things you have to keep in mind when creating a bonus lecture are, for example:
The bonus lecture is your marketing tool
The bonus lecture has to be the last lecture of your course
The title of the bonus lecture must include the word "bonus."
Please click here to learn more about the rules and guidelines for bonus lectures.
If you have more specific questions, please reach out to our policy team at policy@udemy.com.
I hope this helps!
