description	Step-by-step install guidance for Node.js, Python, and Git for beginners. Use when the user cannot run npm/python, says they are new, or asks how to install tools.

Setup — Dev Environment

Guide non-developers through installing necessary tools. All instructions must be completable via copy-paste.

Node.js Installation

1. Go to https://nodejs.org
2. Click the green button (LTS) to download
3. Run the installer
4. Close and reopen the terminal after installation

Python Installation

1. Go to https://www.python.org/downloads/
2. Click the yellow "Download Python" button
3. Windows: CHECK the "Add Python to PATH" checkbox at the bottom
4. Run the installer
5. Close and reopen the terminal after installation

Git Installation

• Mac: Run xcode-select --install in terminal
• Windows: Download from https://git-scm.com and install

How to Open Terminal

• Mac: Press Command + Space, type "Terminal", click the app
• Windows: Press the Windows key, type "cmd" or "Command Prompt", click it

Verify Installation

After installing a tool, always run the verification command:

node --version    # Node.js
python --version  # Python
git --version     # Git

If a version number appears, it worked.

Guidance Principles

• List every step with numbers (1, 2, 3...)
• Provide commands that can be completed via copy-paste
• Tell them what to expect ("if you see a number, it worked")
• Install one tool at a time
• Always remind to close and reopen the terminal after installation
