How do I buy convex Finance?

Excuse me, could you please elaborate on the process of purchasing Convex Finance? I'm quite new to the world of cryptocurrency and finance, and I'm unsure of the steps I need to take to acquire Convex Finance. Is there a specific exchange or platform that I should use? Do I need to create a digital wallet first? Also, are there any specific risks or considerations that I should be aware of before making a purchase? I would greatly appreciate any guidance you can provide.
