## Overview
This is a simple VS Code clone built with React and Monaco Editor.
## Features
- File tree navigation
- Tab management
- Code editing with Monaco Editor
- Syntax highlighting
## Getting Started
1. Create a new file using the + button in the sidebar
2. Edit your code in the editor
3. Save changes using the save button
