How to use Gemini for coding?

Excuse me, but I'm a bit confused by your question. Gemini is a cryptocurrency exchange platform, not a coding tool or programming language. It's used for buying, selling, and storing digital currencies like Bitcoin and Ethereum. Could you perhaps clarify what you mean by "using Gemini for coding"? If you're looking for a way to integrate Gemini into your coding projects or applications, you might be interested in their API, which allows developers to build custom software that interacts with Gemini's platform. But, again, Gemini itself is not a tool for coding.
