+# Complete Setup Guide
+
+## Prerequisites
+Before setting up this project, ensure you have the following installed:
+- **Node.js** (v18+)
+- **Python** (v3.10+)
+- **pip** (Python package installer)
+- **npm** or **yarn**
+
+## Backend Setup
+
+### 1. Navigate to Backend Directory
+```bash
+cd backend
+```
+
+### 2. Create Virtual Environment
+```bash
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+```
+
+### 3. Install Dependencies
+```bash
+pip install -r requirements.txt
+```
+
+### 4. Start Backend Server
+```bash
+uvicorn main:app --reload --host 0.0.0.0 --port 8000
+```
+
+The backend will be available at `http://localhost:8000`
+
+## Frontend Setup
+
+### 1. Navigate to Frontend Directory
+```bash
+cd frontend
+```
+
+### 2. Install Dependencies
+```bash
+npm install
+# or
+yarn install
+```
+
+### 3. Start Development Server
+```bash
+npm run dev
+# or
+yarn dev
+```
+
+The frontend will be available at `http://localhost:3000`
+
+## Using 3D Visualizations
+
+The platform now includes two advanced 3D visualization components:
+
+### ThreatGlobe3D
+Visualizes global threat distribution on an interactive 3D globe.
+
+```tsx
+import ThreatGlobe3D from '@/components/ThreatGlobe3D';
+
+const threats = [
+  { id: 1, position: [1, 0, 0], severity: 'high', type: 'malware' },
+  { id: 2, position: [0, 1, 0], severity: 'critical', type: 'ddos' },
+];
+
+<ThreatGlobe3D threats={threats} />
+```
+
+### NetworkGraph3D
+Shows network topology with 3D interactive nodes and connections.
+
+```tsx
+import NetworkGraph3D from '@/components/NetworkGraph3D';
+
+const nodes = [
+  { id: 'server1', label: 'Main Server', position: [0, 0, 0], type: 'server' },
+  { id: 'client1', label: 'Client', position: [2, 1, 0], type: 'client' },
+];
+
+const edges = [
+  { source: 'server1', target: 'client1', strength: 0.8 },
+];
+
+<NetworkGraph3D nodes={nodes} edges={edges} />
+```
+
+## Environment Variables
+
+Create a `.env` file in the backend directory:
+```
+DATABASE_URL=sqlite:///./security.db
+SECRET_KEY=your-secret-key-here
+ALGORITHM=HS256
+```
+
+Create a `.env.local` file in the frontend directory:
+```
+NEXT_PUBLIC_API_URL=http://localhost:8000
+```
+
+## Troubleshooting
+
+### Backend Issues
+- **Port Already in Use**: Change the port in the uvicorn command
+- **Module Not Found**: Ensure all dependencies are installed and venv is activated
+
+### Frontend Issues
+- **3D Components Not Rendering**: Ensure Three.js dependencies are installed
+- **API Connection Failed**: Check backend is running and CORS is configured
+
+## Production Deployment
+
+### Backend
+```bash
+uvicorn main:app --host 0.0.0.0 --port 8000
+```
+
+### Frontend
+```bash
+npm run build
+npm start
+```
+
+## Docker Setup (Optional)
+
+Build and run with Docker Compose:
+```bash
+docker-compose up --build
+```
