How to buy LTC on Coinbase?

Could you please explain to me the process of purchasing Litecoin (LTC) on the Coinbase platform? I'm a bit unfamiliar with the steps involved and would appreciate a step-by-step guide. For instance, do I need to create an account first? How do I fund my Coinbase wallet? Are there any fees associated with buying LTC? Also, is there a minimum purchase amount? I'm keen on investing in LTC but want to ensure I do it correctly and efficiently. Thank you for your assistance.
