You can use Claude Code even if you’ve never used a terminal before. This guide walks you through opening a terminal, installing Claude Code, and your first interactions.
Don’t want to use the terminal? The Claude Code desktop app lets you skip the terminal entirely. Download it for macOS, Windows, or Linux, then see the Desktop quickstart to get started.

​
macOS and Linux

Follow these steps to install and start Claude Code from a macOS or Linux terminal. Claude Code requires macOS 13.0 or later. See the system requirements for supported Linux distributions.
1

Open a terminal

macOS: Press Cmd + Space to open Spotlight Search, type Terminal, and press Enter.Linux: Open your terminal app. On most distributions, press Ctrl + Alt + T or search for “Terminal” in your application menu.A window will appear with a blinking cursor. This is your terminal, where you type commands.
2

Install Claude Code

Copy this line, paste it into your terminal (Cmd + V on macOS, Ctrl + Shift + V on Linux), and press Enter:
curl -fsSL https://claude.ai/install.sh | bash
This downloads and runs the Claude Code installer from claude.ai. You’ll see text scrolling as it works. When it’s done, you’ll see “Claude Code successfully installed!” If you see an error instead, check the troubleshooting section below.
3

Start Claude Code

Type claude and press Enter:
claude
You’ll be prompted to log in with your Claude account. Follow the on-screen instructions. A browser window will open for you to sign in.
4

Start using Claude Code

Once logged in, you can start asking Claude questions about your code or anything else. Claude Code runs entirely in text. You type messages and press Enter to send them. A few things to know:
  • You can’t click on things in the terminal. Use the arrow keys to move around.
  • Press Esc to interrupt Claude if it’s running.
  • Type exit or press Ctrl + D to leave Claude Code.
  • Type /help to see available commands.

​
Windows

Follow these steps to optionally install Git for Windows, set up PowerShell, and start Claude Code on Windows. Claude Code requires Windows 10 version 1809 or later. See the system requirements for full details.
1

Install Git for Windows (optional)

Git for Windows provides Git Bash, which enables the Bash tool. Without it, Claude Code uses PowerShell instead. You won’t need to learn Git yourself.If you don’t already have it:
  1. Go to git-scm.com/downloads/win and download the installer
  2. Run the installer. Click Next on each screen to accept the defaults. The installer has many screens, but you don’t need to change anything.
  3. If it asks you to choose an editor, keep the default and click Next.
  4. When you see “Adjusting your PATH environment,” keep the recommended option selected.
Already have Git? You can skip this step. If you’re not sure, install it anyway. Reinstalling won’t cause problems.
2

Open PowerShell

PowerShell is Windows’ built-in terminal for typing commands. It comes pre-installed on every Windows computer.Press Win + X and select Windows PowerShell (or Terminal) from the menu. A window with a blinking cursor will appear. This is where you’ll type commands.
Windows has two command-line programs: PowerShell and CMD. They look similar but use different commands. Make sure you’re in PowerShell for the next step.How to tell which one you’re in:
  • PowerShell: shows PS C:\Users\YourName> at the start of each line
  • CMD: shows C:\Users\YourName> without the PS
3

Install Claude Code

Copy this line, paste it into PowerShell with Ctrl + V or right-click, and press Enter:
irm https://claude.ai/install.ps1 | iex
This downloads and runs the Claude Code installer. irm fetches the file and iex runs it. You’ll see text scrolling as it works. When it’s done, you’ll see “Claude Code successfully installed!” If you see an error instead, check the troubleshooting section below.
If you’re in CMD instead of PowerShell, use this command:
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd
4

Start Claude Code

Run claude. If PowerShell says 'claude' is not recognized, the install directory isn’t on your PATH yet. Follow the ‘claude is not recognized’ fix below, then open a new PowerShell window and try again.
claude
You’ll be prompted to log in with your Claude account. Follow the on-screen instructions. A browser window will open for you to sign in.

Once logged in, you can start asking Claude questions about your code or anything else. Claude Code runs entirely in text. You type messages and press Enter to send them. A few things to know:
  • You can’t click on things in the terminal. Use the arrow keys to move around.

  • Type /help to see available commands.

​
What’s next?

Once you see the Claude Code welcome screen, you’re ready to go. You don’t need to know how to code. Describe what you want in plain English, and Claude writes the code for you.

​
Build something

Claude can create projects from a description: 
make me a simple webpage that says hello world
Claude creates the files for you. Double-click the HTML file to open it in your browser.

​
Work with files on your computer

Claude can read and organize files you already have: 
look at the screenshots on my Desktop and rename them based on what's in each image

​
Ask questions

Claude can explain things, help you learn, or plan out a project: 
I want to build a personal budget tracker. What would I need?
If you don’t have a project yet, that’s fine. Claude can help you start a new one.

Troubleshooting

​
macOS and Linux troubleshooting

If you run into problems installing on macOS or Linux, check these common issues:
If you see command not found: claude after installing, the folder where the installer put claude isn’t in your PATH. The installer prints the exact fix under Setup notes at the end of the install, so run that command, or use the one for your shell below.For Zsh, the macOS default shell:
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
For Bash, the Linux default shell:
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
Then open a new terminal and try claude again. If it still isn’t found, check that the file ~/.local/bin/claude exists. If it doesn’t, the install didn’t finish. For more details, see fix your PATH.
If you see bash: line 1: syntax error near unexpected token '<' or HTML code like <!DOCTYPE html> in your terminal, the install URL returned a web page instead of the installer script.If the page says “App unavailable in region,” Claude Code is not available in your country. See supported countries.Otherwise, try running the command again. If it keeps happening, install with Homebrew instead:
brew install --cask claude-code
If you see dyld: cannot load, dyld: Symbol not found, or built for Mac OS X 13.0, your macOS version is likely older than Claude Code supports.Open the Apple menu and select About This Mac to check your version. If it’s older than 13.0, update macOS through Software Update. See the macOS troubleshooting guide for more details.
For other errors, see the full installation troubleshooting guide.

​
Windows troubleshooting

If you run into problems installing on Windows, check these common issues:
You’re in CMD, not PowerShell. Close this window and open PowerShell instead (Win + X then select Windows PowerShell).Alternatively, use the CMD install command:
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd
This usually happens on older Windows 10 systems. Run this line first, then retry the install:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
irm https://claude.ai/install.ps1 | iex
Neither PowerShell nor Git Bash was found. Claude Code needs at least one shell.
  1. Ensure powershell.exe is on your PATH. Its default location is C:\Windows\System32\WindowsPowerShell\v1.0\. Alternatively, install PowerShell 7, which provides pwsh.
  2. If you’d rather use Git Bash, install Git for Windows per the first step in the Windows section.
  3. If Git is installed but Claude Code can’t find it, tell it where to look: 
    $env:CLAUDE_CODE_GIT_BASH_PATH="C:\Program Files\Git\bin\bash.exe"
    Then run claude again. If your Git is installed somewhere else, find the path by running: 
    Get-Command git | Select-Object Source
    Look for the Git\bin folder in that path and use it instead.
To make this permanent so you don’t have to set it every time, see configure Git Bash path.
This error means the install directory isn’t in your PATH. Run these commands in PowerShell to add it:
$currentPath = [Environment]::GetEnvironmentVariable('PATH', 'User')
[Environment]::SetEnvironmentVariable('PATH', "$currentPath;$env:USERPROFILE\.local\bin", 'User')
Close PowerShell, open a new window, and try claude again. See verify your PATH for more details.
For other errors, see the full installation troubleshooting guide.
