Can I buy ETH in Coinbase?

Could you please elaborate on the process of purchasing ETH on Coinbase? I'm quite interested in adding it to my crypto portfolio, but I'm not entirely sure how to proceed. Is it a straightforward process? Do I need to have a specific account setup or meet certain requirements? Also, are there any fees associated with buying ETH on Coinbase? I'd appreciate it if you could provide a step-by-step guide on how to go about this purchase, including any important considerations I should take into account.
