Claude Code Quickstart: Install, Log In, and Make Your First Code Change
This guide walks through getting started with Claude Code, Anthropic's terminal-based coding tool. It covers installing Claude Code on macOS, Linux, Windows, and WSL using the native installer, Homebrew, or WinGet, then logging in with a Claude subscription, Console account, or enterprise cloud provider. From there it shows how to start a session in a project directory, ask questions about a codebase, make a first code change with permission modes, and use Git conversationally. It is based on Anthropic's official quickstart documentation.
