| - -**First time doing AI coding?** - -Day one becomes setup day. Git is missing, the Node version is wrong, and the terminal prints an error you have no way to rank. - -→ Don't stall at setup — **start your first project today.** - -[Quick start ↓](#quick-start) - - | -- -**Setting up a second Mac (a new mini)?** - -Every new machine turns into an archaeology session about what you installed last time, and the machines drift apart from there. - -→ Don't memorize your environment — **reproduce it.** - -[A second Mac ↓](#a-second-mac-or-a-fresh-reinstall) +## What is this? - | -+A fresh laptop or PC usually means installing Git, runtimes, terminal tools, +Docker, and AI coding agents one by one. -**Teaching AI coding?** +lazy-starter-kit bootstraps that development environment in one pass and gives +you a way to verify the result afterwards. -The first bottleneck in a class is never prompting — it's everyone's basic setup. One person has no Git, another is opening a terminal for the first time. +Main components include: -→ Stop teaching installs — **teach building.** +- CLI: git, gh, jq, ripgrep, fd, fzf, bat, tree, ast-grep, zoxide +- Runtimes: Node.js, Python, Go, Rust +- Shell/prompt: zsh, oh-my-zsh, starship, Nerd Font +- Containers: Colima on macOS, Docker Engine on Linux, optional Docker Desktop on Windows +- AI agents: Claude Code, gajae-code, Codex, lazycodex -[Class setup ↓](#running-a-class-or-study-group) +Existing tools are left alone where practical, and managed configuration files +are edited only inside clearly marked blocks. Use `--doctor` to inspect the +current state and `--dry-run` to preview changes before applying them. - | -
