+# 🖥️ GNS3 VNC Appliance Template
+
+> **Base Image**: `git.merith.xyz/gns3/base-vnc:latest`  
+Create custom VNC appliances for GNS3 with automatic startup scripts.
+
+---
+
+## 🚀 Quick Start
+
+1. **Clone the template**:
+```bash
+git clone https://git.merith.xyz/gns3/vnc-template.git
+cd vnc-template
+```
+
+2. **Customize your appliance**:
+```dockerfile
+FROM git.merith.xyz/gns3/base-vnc:latest
+
+## ADD YOUR CUSTOMIZATIONS HERE ##
+RUN apk add --no-cache firefox-esr xterm
+
+## END CUSTOMIZATION ##
+COPY ./entrypoint.sh /entrypoint.sh
+RUN chmod +x /entrypoint.sh
+```
+
+3. **Configure startup** (`entrypoint.sh`):
+```bash
+#!/bin/bash
+# Start your applications automatically:
+firefox &  # Launch in background
+xterm      # Keep terminal open
+```
+
+4. **Build and push**:
+```bash
+docker build -t your-registry/vnc-firefox:latest .
+docker push your-registry/vnc-firefox:latest
+```
+
+---
+
+## 🔧 GNS3 Appliance Configuration
+
+1. In GNS3, create new **Docker VM** template:
+   - **General Settings**:
+     - Name: `Your-Appliance-Name`
+     - Docker image: `your-registry/vnc-firefox:latest`
+   - **Network**:
+     - `eth0` = `Management` (NAT)
+     - Additional NICs as needed
+   - **Console**:
+     - Type: `VNC`
+     - Port: `5900`
+
