How to buy dollars on Shyft?

Excuse me, could you please clarify the process of buying dollars on Shyft? I'm a bit new to the platform and I'm interested in understanding the steps I need to follow to successfully make a purchase. Specifically, I'd like to know if there are any prerequisites, such as verifying my identity or setting up a wallet, and if so, how do I go about doing that? Additionally, could you walk me through the actual buying process, from selecting the amount of dollars I want to purchase to finalizing the transaction? I appreciate your help and guidance in this matter.
