Can I buy small amount of BNB?

Excuse me, I'm quite new to the world of cryptocurrencies and I'm still trying to wrap my head around it. I've heard a lot about BNB and its popularity in the crypto community. I'm just wondering, is it possible for me to buy a small amount of BNB? I don't want to invest a lot initially, just to see how it goes. Could you please guide me on how to proceed with such a small purchase? I'd really appreciate it if you could help me understand the steps involved in this process.
