How do I buy on Binance Dex?

As a crypto enthusiast, I'm curious about the process of buying on Binance Dex. Could you walk me through the steps? Firstly, I understand that I need to create an account and set up a wallet on Binance Dex. After that, how do I deposit funds into my wallet? Do I have to use a specific cryptocurrency, or are there multiple options? Once my funds are in, how do I find the asset I want to purchase? And finally, how do I execute the trade and ensure it's successful? Any tips or advice you could offer to ensure a smooth and secure transaction would be greatly appreciated.
