Want to stop breastfeeding

Baby was born 11/10. I just can’t do breastfeeding. I’ve decided to stop and switch to formula. How do I do this? Do I just stop, and my supply will start to go away. I’m not sure if my milk is quite in yet. Boobs are bigger and some leaking. I just didn’t know if I had to do anything specific for my boobs, or if I can just stop? I don’t want to pump either. Just advice please no opinions.
