How to buy Litecoin?

Could you please elaborate on the process of purchasing Litecoin? I'm interested in understanding the steps involved from scratch, starting with setting up a cryptocurrency wallet. Could you also explain what kind of exchanges I could use to make the purchase, and any safety measures I should take while engaging in such transactions? Additionally, I'm curious about the fees associated with buying Litecoin and whether there are any limitations or restrictions I should be aware of. Thank you for your assistance in guiding me through this process.
