Quickstart
Welcome to Claude Code!
This quickstart guide will have you using AI-powered coding assistance in just a few minutes. By the end, you’ll understand how to use Claude Code for common development tasks.
Before you begin
Make sure you have:
- A terminal or command prompt open
- A code project to work with
- A Claude.ai (recommended) or Anthropic Console account
Step 1: Install Claude Code
NPM Install
If you have Node.js 18 or newer installed:
Native Install
Alternatively, try our new native install, now in beta.
macOS, Linux, WSL:
Windows PowerShell:
Step 2: Log in to your account
Claude Code requires an account to use. When you start an interactive session with the claude
command, you’ll need to log in:
You can log in using either account type:
- Claude.ai (subscription plans - recommended)
- Anthropic Console (API access with pre-paid credits)
Once logged in, your credentials are stored and you won’t need to log in again.
When you first authenticate Claude Code with your Anthropic Console account, a workspace called “Claude Code” is automatically created for you. This workspace provides centralized cost tracking and management for all Claude Code usage in your organization.
You can have both account types under the same email address. If you need to log in again or switch accounts, use the /login
command within Claude Code.
Step 3: Start your first session
Open your terminal in any project directory and start Claude Code:
You’ll see the Claude Code prompt inside a new interactive session:
After logging in (Step 2), your credentials are stored on your system. Learn more in Credential Management.
Step 4: Ask your first question
Let’s start with understanding your codebase. Try one of these commands:
Claude will analyze your files and provide a summary. You can also ask more specific questions:
You can also ask Claude about its own capabilities:
Claude Code reads your files as needed - you don’t have to manually add context. Claude also has access to its own documentation and can answer questions about its features and capabilities.
Step 5: Make your first code change
Now let’s make Claude Code do some actual coding. Try a simple task:
Claude Code will:
- Find the appropriate file
- Show you the proposed changes
- Ask for your approval
- Make the edit
Claude Code always asks for permission before modifying files. You can approve individual changes or enable “Accept all” mode for a session.
Step 6: Use Git with Claude Code
Claude Code makes Git operations conversational:
You can also prompt for more complex Git operations:
Step 7: Fix a bug or add a feature
Claude is proficient at debugging and feature implementation.
Describe what you want in natural language:
Or fix existing issues:
Claude Code will:
- Locate the relevant code
- Understand the context
- Implement a solution
- Run tests if available
Step 8: Test out other common workflows
There are a number of ways to work with Claude:
Refactor code
Write tests
Update documentation
Code review
Remember: Claude Code is your AI pair programmer. Talk to it like you would a helpful colleague - describe what you want to achieve, and it will help you get there.
