Before editing the theme, make sure you have:
  • Node.js (Latest LTS recommended)
  • A code editor (VS Code is recommended)

Check your Node.js installation

If Node.js is not installed, download it from nodejs.org. After installation, verify everything works:
  • node -v
  • npm -v
  • npx -v
If all commands return version numbers, you’re ready to continue.
