Thanks for asking.
Well staging and production in licence manager page is there for the reason being, generally website is developed on a staging server and then moved to production setup. However, lot of developers design and build websites on the production setup too. So, there is no hard and fast rule ( though it's recommended) that one has to develop the website on staging and then move to production. You are free and develop directly on the production setup also.
For more information, please take a look at our product validation guide.
