How do I access Google Gemini?

Excuse me, could you please clarify how one might gain access to Google Gemini? I've been hearing a lot about it lately and I'm quite intrigued, but I'm not entirely sure where to start. Is it a separate platform that I need to sign up for, or is it integrated into an existing Google service? Are there any specific requirements or qualifications that need to be met in order to access it? Any information you could provide would be greatly appreciated.
