How do I buy SOL on Binance?

I'm interested in purchasing SOL on Binance, but I'm not sure where to start. Could you guide me through the process? I'm looking for a step-by-step explanation of how to navigate the platform and make a successful purchase. Are there any fees I should be aware of? And how can I ensure that my transaction is secure? I'm new to crypto and would appreciate any tips or advice you can offer.
