How to buy KCS on MetaMask?

As a crypto enthusiast, I'm curious about the process of acquiring KCS tokens through MetaMask. Could you please provide a step-by-step explanation of how to do so? I've heard that MetaMask is a popular wallet for managing Ethereum-based tokens, but I'm not entirely sure how to navigate the interface and complete the purchase of KCS. I'd appreciate any details you can offer, from adding the KCS token contract address to MetaMask to the actual purchase process. Thank you in advance for your assistance!
