How to get an FEI?

Excuse me, could you please elaborate on the process of acquiring an FEI? I understand that it stands for Fractional-Algorithmic Stablecoin, but I'm not entirely sure how to go about acquiring one. Do I need to trade it for another cryptocurrency? Can I buy it directly with fiat currency? And, is there a specific platform or exchange where I can find and purchase FEI? Any guidance you can provide would be greatly appreciated.
