Walks you through setting up dev environments from scratch with platform-specific install commands for macOS, Linux, and Windows. Covers the full cycle: checking what's already installed, installing tools like Node or Python, configuring environment variables and dotfiles, then verifying everything works. Includes complete examples for Node.js, Python with venv, and Docker Compose setups. The troubleshooting sections are genuinely helpful, like fixing npm permissions without sudo. If you're onboarding someone new or documenting setup for a project, this gives you a solid template instead of writing instructions from memory and inevitably forgetting something.
