I have a french passport and I just moved to France. What is the process of being a citizen/what papers and documents to I need to possess to be able to work and go to school and live?

I know I need a Carte Vitale, Social Security Number, an ID card. But from my understanding, most of that gets done through your employer/school, and I have none. So i'm kind of lost.

Thank you for any help!
