+# Quick Start Guide
+
+## Overview
+
+This guide will help you get the Telecom-as-a-Service platform running in minutes.

+```bash
+# Clone the repository (if not already done)
+git clone https://github.com/nutcas3/telecom-platform.git
+cd telecom-platform
+
+# Install dependencies
+make install-deps
+```
+
+## 2. Start Core Services
+
+```bash
+# Start databases and core services
+docker-compose up -d mongodb redis
+
+# Start free5GC core network
+make free5gc-start
+
+# Start application services
+docker-compose up -d api-server charging-engine carrier-connector
+```
+
+## 3. Start Development Server
+
+```bash
+# Start web dashboard
+make dev-ui
+```
+
+## 4. Verify Deployment
+
+```bash
+# Check all services status
+make verify
+
+# Test free5GC configuration
+make free5gc-test
+```
+
+## 5. Access Services
+
+- **Web Dashboard**: http://localhost:3000
+- **API Server**: http://localhost:8000
+- **Charging Engine**: http://localhost:8080
+
+## 6. Common Commands
+
+```bash
+# View free5GC logs
+make free5gc-logs
+
+# Stop all services
+docker-compose down
+
+# Rebuild services
+make docker-build
+
+# Clean everything
+make clean
+```
+
+## Service Architecture
+
+```

+    |
+[Web Dashboard] - [API Server] - [Carrier Connector]
+    |               |               |
+    |           [Charging Engine]  |
+    |               |               |
+    +-----------[free5GC Core]-----+
+                    |
+                [MongoDB] [Redis]
+```
+
+## Troubleshooting
+
+### Services Not Starting
+```bash
+# Check logs
+docker-compose logs [service-name]
+
+# Restart specific service
+docker-compose restart [service-name]
+```
+
+### Port Conflicts
+Ensure ports 3000, 8000, 8080, 27017, 6379 are available.
+
+### Permission Issues
+```bash
+# Fix script permissions
+chmod +x scripts/*.sh
+```
+
+## Next Steps
+
+1. Explore the API documentation at `/docs/API.md`
+2. Configure your first subscriber in the web dashboard
+3. Test the charging engine with sample data
+4. Deploy to Kubernetes using the provided manifests
