How do I buy Solana on Coinbase?

Hello, I'm considering adding Solana to my crypto portfolio but I'm a bit new to this. Could you please guide me through the process of purchasing Solana on Coinbase? I've heard it's a popular exchange but I'm not sure how to navigate it for buying specific cryptocurrencies. Could you walk me through the steps from signing in to confirming the purchase? Any tips or advice on things to look out for during the process would also be greatly appreciated. Thank you for your help!
