Setup — Dev Environment
Guide non-developers through installing necessary tools. All instructions must be completable via copy-paste.
Node.js Installation
- Go to https://nodejs.org
- Click the green button (LTS) to download
- Run the installer
- Close and reopen the terminal after installation
Python Installation
- Go to https://www.python.org/downloads/
- Click the yellow "Download Python" button
- Windows: CHECK the "Add Python to PATH" checkbox at the bottom
- Run the installer
- 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
python --version
git --version
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
