Install the whole stack in one command

Fresh Mac? This takes you from nothing to a fully-configured Claude Code + Ghostty — no git, Homebrew, or Node needed first. The script installs the whole stack for you.

bash

curl -fsSL https://raw.githubusercontent.com/bogdanmatasaru/claude-code-guide/main/install.sh | bash

Then open Ghostty, type claude, and log in. That's it. → Full setup guide

What that one command does

It runs an idempotent, re-runnable bootstrap that installs and configures everything, in order:

Step	What it sets up
1	Xcode Command Line Tools — git & compilers
2	Homebrew — the macOS package manager
3	Ghostty + JetBrains Mono — the recommended terminal
4	Node.js + GitHub CLI
5	Claude Code — the `claude` CLI
6	Configs — Ghostty theme, `~/.claude` settings, shell PATH & aliases
7	Live status line — model · context · 5h/weekly limits · branch · session · disk

TIP

Want to preview it first, changing nothing? Add --dry-run: curl -fsSL …/install.sh | bash -s -- --dry-run. Already set up? Run ./setup.sh --check anytime to validate your environment.

Prefer to do it step by step, or not on a Mac? See the installation guide and the one-command setup page.
