How do I sell core from MetaMask?

Hey there, I'm curious about something. I've been holding some CORE tokens in my MetaMask wallet, and now I'm thinking about selling them. Can you help me out with the process? I'm not really sure how to go about it. Is there a specific exchange I should use, or a particular step-by-step process I should follow? I'd really appreciate any guidance you can offer. Thanks in advance!
