Setting up Claude Code

To set up Claude Code, you first install the CLI tool through your terminal using a single command tailored to your operating system. For macOS, Linux, or WSL, you run curl -fsSL https://claude.ai/install.sh | bash, while Windows users can use PowerShell to run irm https://claude.ai/install.ps1 | iex. Once the installation is complete, you navigate to any code project directory and type claude, which will trigger a one-time login process where you authenticate using your Claude account or an Anthropic Console API key. After logging in, the tool is ready to use immediately.
