How do you buy Renzo?

Excuse me, could you possibly explain to me the process of purchasing Renzo? I'm quite interested in adding it to my portfolio, but I'm not entirely sure where to start. Do I need to register on a specific exchange? Are there any specific steps I should follow? Also, are there any fees associated with the purchase? It would be greatly appreciated if you could provide me with a step-by-step guide on how to buy Renzo.
