How to rent out a car safely?

Hi! I have a car that I rarely use, and I'm thinking about renting it out. But I don't know where to start. I'd like to understand how to rent out a car safely so that there are no problems. Maybe someone has already rented out their car? What were your impressions? Share your experience: what should I pay attention to, where is the best place to post ads, and what documents should I prepare? I'm also interested in how to conclude a contract with a client and protect myself in case something happens to the car. Thanks in advance for any advice!
