How to add telos to MetaMask?

Could you please elaborate on the process of adding Telos to MetaMask? I'm a bit of a newcomer to the world of cryptocurrencies and would greatly appreciate a step-by-step guide. Specifically, I'm wondering if there's a specific network I need to select or a custom token I should add. Additionally, would I need to acquire Telos tokens beforehand or can I do so directly through MetaMask? Any guidance you could provide would be invaluable as I aim to expand my portfolio into new digital assets.
