How to swap ETH for ADA?

Excuse me, could you please clarify the process for swapping Ethereum (ETH) for Cardano (ADA)? I'm a bit new to this and would appreciate a step-by-step guide on how to go about it. Do I need to have a specific wallet or exchange platform? Are there any fees involved, and if so, how much can I expect to pay? Additionally, are there any security measures I should take into consideration to ensure a smooth and secure transaction? I'd be grateful for any insights or advice you can offer.
