+# MeshVPN - High Performance Overlay Network
+
+A production-grade, lightweight mesh VPN solution designed for zero-config connectivity.
+
+## 🚀 Overview
+MeshVPN allows you to create a secure, peer-to-peer encrypted network across Windows, macOS, and Linux without requiring manual port forwarding.
+
+### Key Features
+- **All-in-One Coordinator**: Integrated STUN, Coordination, and WebUI.
+- **Zero-Config Onboarding**: Join a network using a single shared "Network Key".
+- **Extreme Performance**: Rust-based data plane with memory footprint < 256MB.
+- **NAT Traversal**: Advanced UDP hole punching and blind relay (DERP) support.
+- **Professional UI**: Enterprise-grade glassmorphism dashboard for server monitoring.
+
+## 📂 Project Structure
+- `/server`: Go-based Coordinator, STUN, and Web Dashboard.
+- `/client`: Rust-based cross-platform client agent.
+- `install_meshvpn.sh`: Automated one-click VPS deployment script.
+- `/docs`: Technical specifications and deployment guides.
+
+## 🛠 Installation
+
+### Server (VPS)
+Run the automated installer on your Ubuntu VPS:
+```bash
+chmod +x install_meshvpn.sh
+sudo ./install_meshvpn.sh
+```
+Then start the server:
+```bash
+cd ~/meshvpn/server && go run main.go
+```
+
+### Client (Windows/Linux/macOS)
+1. Install the [Rust toolchain](https://rustup.rs/).
+2. Build the release binary:
+   ```bash
+   cargo build --release
+   ```
+3. Run as Administrator/Root.
+
+## 🛡 Security
+- **E2EE**: All traffic is encrypted via the Noise Protocol (WireGuard).
+- **Zero-Trust Coordination**: The server facilitates introductions but cannot decrypt user traffic.
+- **Identity**: Nodes are identified by a combination of a shared network key and unique public keys.
