+## 📂 Overview
+
+This repository serves as a sandbox for web development experiments. It is designed without a specific single purpose, acting instead as a flexible container for:
+
+- Testing raw HTML files
+- Prototyping web concepts
+- Serving static assets
+- Debugging code snippets
+
+## 🚀 Features
+
+- **Directory Indexing**: Serves as a basic file explorer to easily navigate through various test files.
+- **Vercel Integration**: Automatically deployed and hosted on Vercel for instant sharing and access.
+- **Minimalist Structure**: No complex build steps or heavy frameworks—just raw web technologies.
+
+## 🔗 Live Access
+
+This project is connected to a custom domain and serves files directly via a directory listing interface.
