How do I buy Solana on Metamask?

Could you please enlighten me on the process of purchasing Solana tokens using Metamask? I'm quite interested in adding this cryptocurrency to my portfolio, but I'm a bit unclear on the exact steps involved. Could you guide me through the necessary procedures, such as setting up an account, connecting to the appropriate network, and making the purchase itself? I'd also appreciate any insights on potential fees or considerations I should be aware of before making the transaction. Thank you in advance for your assistance.
