Great job on creating CodeGPT.nvim! This plugin for neovim seems like a useful tool for code-related tasks such as code completion, refactoring, and generating documentation. The clear instructions for installation, including setting the environment variable and required plugins, make it easy for users to get started. The use of the ChatGPT API is also an exciting feature that adds a unique aspect to the plugin. Overall, I appreciate your hard work in developing this tool and look forward to seeing how it continues to evolve. Keep up the good work!
