-# OpenNetworkDiagram
+# **Open Network Diagram**
+
+**A declarative, self-hosted tool for visualising and managing home lab & network architecture diagrams.**
+
+---
+
+## **📝 About**
+
+**Open Network Diagram** is an **open-source, self-hosted tool** for creating **interactive network and infrastructure diagrams** using a **declarative JSON format**.
+
+✅ **Fully self-hostable via Docker**  
+✅ **JSON-based network structure** (editable in UI or manually)  
+✅ **Interactive network visualisation**  
+✅ **Persistent storage of network configurations**  
+✅ **Lightweight Svelte + Express.js**
+
+Use it to **document your home lab, office network, or cloud infrastructure** with an easy-to-use web interface.
+
+---
+
+## **🚀 Quick Start (For Users)**
+
+### **1️⃣ Run Open Network Diagram via Docker**
+
+Pull and run the latest image:
+
+```bash
+docker run -d -p 8080:3000 -v /path/to/data:/data jcreek23/open-network-diagram
+```
+
+- **`-p 8080:3000`** → Maps the app to `http://localhost:8080`
+- **`-v /path/to/data:/data`** → Mounts a folder for persistent `network.json` storage
+
+### **2️⃣ Open the Web UI**
+
+Visit **`http://localhost:8080`** to view and edit your network diagram.
+
+### **3️⃣ Modify Your Network (JSON-Based)**
+
+- The app reads **`network.json`** from the **mounted `/data` directory**.
+- Use the **web UI** to edit and save network changes.
+
+---
+
+## **👩‍💻 Development Setup**
+
+### **1️⃣ Clone the Repository**

+## **📦 Docker Build & Deployment**
+
+### **Build the Docker Image Locally**
+
+```bash
+docker build -t open-network-diagram .
+```
+
+### **Run Locally**
+
+```bash
+docker run -p 8080:3000 -v /path/to/data:/data open-network-diagram
+```
+
+### **CI/CD (GitHub Actions)**
+
+- Automatic Docker builds when changes are pushed to `main`.
+- Pushes the latest image to **Docker Hub**.
+

+
+## **📝 JSON Network Configuration Example**
+
+Define your network using **`network.json`**:
+
+```json
+{
+  "machines": [
+    {
+      "machineName": "ProxRouter",
+      "ipAddress": "10.0.0.3",
+      "role": "Hypervisor",
+      "operatingSystem": "Proxmox",
+      "software": {
+        "vms": [
+          { "name": "OpnSense", "role": "Router", "ipAddress": "10.0.0.4" },
+          { "name": "PiVPN", "role": "VPN Server", "ipAddress": "10.0.0.5" }
+        ]
+      },
+      "hardware": {
+        "cpu": "Intel N100",
+        "ram": "8GB",
+        "networkPorts": 4
+      }
+    }
+  ]
+}
+```
