Prerequisites

Cline CLI requires Node.js version 20 or higher. We recommend using Node.js 22 for the best experience. To check your Node.js version: 
node --version

​
Installation

npm install -g cline
After installation, authenticate with your Cline account: 
cline auth
This starts an authentication wizard to sign you in and configure your preferred AI model provider.

​
Quick Start

Get started with Cline in seconds: 
cline
That’s it! Running cline in any directory starts an interactive session where you can chat with the AI agent. Type your task, review the plan, and type /act when ready to execute. For even faster execution without interaction: 
cline "Add unit tests to utils.js"
This runs Cline with a single command, perfect for quick tasks or automation.
