What do I need for Vara FM?

Hello there, I'm curious about Vara FM and what requirements I might need to fulfill in order to get started with it. Is there a specific set of hardware or software that's necessary? Are there any prerequisite skills or knowledge that I should have beforehand? Additionally, is there a minimum investment or balance that I need to maintain in order to access its services? I'm looking to get a better understanding of the basics so I can determine if Vara FM is the right fit for me.
