Hi @Naveen29901 welcome to the group! Im pretty sure by now you have an instructor profile.
from here you basically click on create a "new course" button to get started.
You will then maintain the info. about the course e.g. course structure, target students etc. the
page should be able to guide you through the process. Depending on the nature of your course, you may or maynot wana record yourself OR decide to record the screen where you will teach.
You will be required to upload a test vid before you went ahead recording all of the course though.
I wil let others/pros weigh in as well on this.
