How to buy wstETH?

Could you please elaborate on the process of purchasing wstETH? I'm quite interested in adding it to my portfolio, but I'm not entirely sure where to start. Do I need to have a specific wallet or exchange account? Are there any particular steps I should follow to ensure a smooth transaction? Also, is there any advice you could give me on managing the risks associated with investing in wstETH? I'd appreciate any insights you could share.
