+# This script is meant to help you quickly set up
+# JavaScript/TypeScript projects (Node.js, React, etc.)
+# 
+# ⚠️ NOTE:
+#   - For other languages/frameworks (Python, Go, Rust, etc.)
+#     you should adapt or replace this script.
+#   - Example: `pip install -r requirements.txt` for Python,
+#     or `go mod tidy` for Go.
+#
+# Customize this script to fit your project needs!
