How to enable access to Gemini AI?

Could you please explain the steps required to enable access to Gemini AI? I'm interested in utilizing its capabilities but am unsure of the process. Is there a specific registration process I need to complete? Do I need to have a certain level of experience or knowledge in cryptocurrency or finance to be eligible? Additionally, are there any fees associated with accessing Gemini AI, and if so, what are they? Your guidance would be greatly appreciated.
