How to Install Gemini CLI

Getting started is simple and requires only a few steps:

Prerequisites

Ensure you have Node.js v18 or higher installed on your system.

Installation Steps

For Linux/macOS users:

npm install -g @google/gemini-cli

Alternatively, test it instantly without installation:

npx https://github.com/google-gemini/gemini-cli

For Windows users:
Open PowerShell or Windows Terminal (preferably as Administrator) and run the same npm or npx command.

Once installed, launch the interface by typing:

gemini

Authentication & API Key Setup

By default, Gemini CLI uses your personal Google account with the following limits:

For higher usage or access to advanced models like gemini-pro, configure an API key from Google AI Studio:

  1. Visit Google AI Studio and generate your API key.

  2. Set it as an environment variable:

    export GOOGLE_GENAI_API_KEY="your-api-key-here"
  3. To persist across sessions, add the line to your .bashrc or .zshrc file.

Now you're ready to unlock extended capabilities.

Essential Commands for Maximum Efficiency

After launching gemini, use these powerful slash commands to control the experience:

These commands help maintain context and continuity across complex tasks.

File and Project Analysis Made Simple

Gemini CLI excels at understanding file structures and code logic. Use the @ symbol to reference files or directories:

@src/components analyze the architecture of my React components
@. explain how this application works

You can also create a GEMINI.md file in your project root to provide persistent context—perfect for long-term projects.

Automate Shell Tasks with Ease

Need to run system commands? Gemini CLI supports inline shell execution using !:

!git status

Enter full shell mode with:

!.

This allows real-time automation of repetitive tasks like backups, log rotation, or dependency checks.

Real-World Use Cases

Migrate Legacy Codebases

Analyze outdated frameworks and generate migration strategies:

@src/app analyze this Angular code and propose a migration to React

Generate Apps from Design Mockups

Turn PDF mockups into functional code:

@mockup.pdf generate me a React app that implements these screens

Debug Like a Pro

Upload error logs and get intelligent suggestions:

@error.log explain this error and suggest solutions

Automate DevOps Workflows

Create scripts on demand:

“Create a bash script that backs up my database, compresses logs older than 7 days, and sends a report via email.”

The AI generates secure, efficient code instantly.

Auto-Generate Documentation

Keep APIs well-documented:

@src generate complete documentation for this API with usage examples

Integrated Tools for Developer Productivity

Gemini CLI comes equipped with several smart tools:

These tools make Gemini CLI more than just an AI chat—they turn it into a full-stack assistant.
