Can I buy Chainlink on MetaMask?

Excuse me, I'm a bit new to the world of cryptocurrency trading. I've been hearing a lot about Chainlink and I'm interested in adding it to my portfolio. Could you please tell me if it's possible to purchase Chainlink through MetaMask? If so, could you provide a brief outline of the steps involved? I'd appreciate any guidance you can offer. Thank you in advance for your help!
