Welcome to Gemini CLI documentation

This documentation provides a comprehensive guide to installing, using, and developing Gemini CLI. This tool lets you interact with Gemini models through a command-line interface.

Overview

Gemini CLI brings the capabilities of Gemini models to your terminal in an interactive Read-Eval-Print Loop (REPL) environment. Gemini CLI consists of a client-side application (packages/cli) that communicates with a local server (packages/core), which in turn manages requests to the Gemini API and its AI models. Gemini CLI also contains a variety of tools for tasks such as performing file system operations, running shells, and web fetching, which are managed by packages/core.
