+
+A Python-based **real-time collaborative text editor** with diff-based updates, floating colored cursors, and username labels — designed to feel like Google Docs. Built using `ttkbootstrap` for a modern **Flatly theme**.

+
+## 🛠 Requirements
+
+- **Python 3.10+**
+- Python packages:
+```bash
+pip install ttkbootstrap websockets pillow
+```
+
+---
+
+## 📂 Project Files
+
+- `server_diff_graceful.py` – WebSocket server handling diff updates, cursors, and usernames.
+- `client_diff_floating_cursors.py` – Collaborative client with diff-based editing, floating cursors, and username labels.
+- `README.md` – This file.
+
+---
+
+## 🚀 Usage
+
+### 1️⃣ Start the Server
+
+```bash
+python server_diff_graceful.py
+```
+
+- The server runs on `0.0.0.0:8765` by default.
+- Press **Ctrl+C** to stop gracefully.
+
+### 2️⃣ Start a Client
+
+```bash
+python client_diff_floating_cursors.py
+```
+
+- Enter a **unique username** when prompted.
+- The editor window will open. You can start typing and collaborate in real-time.
+
+### 3️⃣ Multi-User Collaboration
+
+- Run multiple clients on the same or different machines connected to the server.
+- Features you’ll see in real-time:
+  - **Floating colored cursors** for each user.
+  - **Username labels** next to cursors.
+  - Live document updates from all collaborators.
+
+---
+
+## ⚙ How It Works
+
+- **Diff-Based Syncing**: Only changes are sent over the network, making it bandwidth-efficient.
+- **Floating Cursors & Labels**: Cursors and labels are drawn visually without modifying the actual text content.
+- **Async + Threaded**: Smooth updates using `asyncio` alongside Tkinter GUI.
+
+---
+
+## 🎨 Customization
+
+- **Server IP / Port**: Modify `SERVER_URI` in `client_diff_floating_cursors.py`.
+- **Cursor Colors**: Edit the `colors_list` variable for different cursor/label colors.
+- **UI Theme**: Change the `themename` in `tb.Window()` to use other `ttkbootstrap` themes.
+
+---
+
+## 💡 Notes
+
+- All clients must connect to the **same server IP and port**.
+- Designed for **text documents**. Very large files may affect Tkinter performance.
+- Ideal for collaborative note-taking, coding experiments, or teaching demos.
