How to earn yield with stETH?

Could you kindly explain to me the process of generating yields with stETH? I've heard it's a popular strategy in the crypto finance world, but I'm still a bit hazy on the specifics. Could you elaborate on the steps involved? Also, what are the potential risks and rewards associated with this approach? I'm particularly interested in understanding the mechanisms behind it and how it differs from other yield-generating strategies. Thank you in advance for your detailed explanation.
