+# Quick Start Guide
+
+Get the Normogen backend running locally in 5 minutes.
+
+## Prerequisites
+
+- Rust 1.70 or later
+- MongoDB 4.4 or later
+- Git
+
+## Step 1: Clone and Setup
+
+```bash
+# Clone repository
+git clone <forgejo-url> normogen
+cd normogen/backend
+
+# Copy environment template
+cp .env.example .env
+```
+
+## Step 2: Start MongoDB
+
+### Option A: Using Docker (Recommended)
+
+```bash
+docker run -d \
+  --name normogen-mongo \
+  -p 27017:27017 \
+  -e MONGO_INITDB_DATABASE=normogen \
+  mongo:latest
+```
+
+### Option B: Using System MongoDB
+
+```bash
+# Start MongoDB service
+sudo systemctl start mongod  # Linux
+brew services start mongodb  # macOS
+```
+
+## Step 3: Configure Environment
+
+Edit `backend/.env`:
+
+```bash
+# MongoDB Configuration
+MONGODB_URI=mongodb://localhost:27017
+DATABASE_NAME=normogen
+
+# JWT Configuration (change this!)
+JWT_SECRET=my-super-secret-jwt-key-32-chars
+JWT_ACCESS_TOKEN_EXPIRY_MINUTES=15
+JWT_REFRESH_TOKEN_EXPIRY_DAYS=30
+
+# Server Configuration
+SERVER_HOST=127.0.0.1
+SERVER_PORT=8000
+```
+
+## Step 4: Build and Run
+
+```bash
+# Install dependencies and build
+cargo build
+
+# Run the server
+cargo run
+```
+
+Server will start on `http://127.0.0.1:8000`
+
+## Step 5: Test
+
+### Health Check
+
+```bash
+curl http://localhost:8000/health
+```
+
+Expected response:
+```json
+{
+  "status": "ok",
+  "database": "connected"
+}
+```
+
+### Register a User
+
+```bash
+curl -X POST http://localhost:8000/api/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "SecurePassword123!"
+  }'
+```
+
+Expected response:
+```json
+{
+  "message": "User registered successfully",
+  "user_id": "...",
+  "email": "test@example.com"
+}
+```
+
+### Login
+
+```bash
+curl -X POST http://localhost:8000/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "SecurePassword123!"
+  }'
+```
+
+Expected response:
+```json
+{
+  "access_token": "...",
+  "refresh_token": "...",
+  "token_type": "Bearer",
+  "expires_in": 900
+}
+```
+
+### Access Protected Endpoint
+
+```bash
+# Replace YOUR_ACCESS_TOKEN with the token from login
+curl http://localhost:8000/api/users/me \
+  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"
+```
+
+Expected response:
+```json
+{
+  "user_id": "...",
+  "email": "test@example.com",
+  "family_id": null,
+  "token_version": 0
+}
+```
+
+## Docker Quick Start
+
+```bash
+cd backend
+
+# Start MongoDB and backend with Docker Compose
+docker compose up -d
+
+# Check logs
+docker compose logs -f backend
+
+# Test
+curl http://localhost:6000/health
+```
+
+## Next Steps
+
+- Read [CONFIG.md](./CONFIG.md) for detailed configuration
+- Read [STATUS.md](./STATUS.md) for development progress
+- Run `./thoughts/test_auth.sh` for comprehensive API testing
+- Check API documentation in [verification-report-phase-2.3.md](./verification-report-phase-2.3.md)
+
+## Troubleshooting
+
+### Port 8000 already in use
+
+```bash
+# Find and kill the process
+lsof -ti:8000 | xargs kill -9
+```
+
+### MongoDB connection failed
+
+```bash
+# Check MongoDB is running
+docker ps | grep mongo
+# or
+systemctl status mongod
+
+# Test connection
+mongosh "mongodb://localhost:27017"
+```
+
+### Compilation errors
+
+```bash
+# Clean and rebuild
+cargo clean
+cargo build
+```
+
+### JWT secret too short
+
+Make sure `JWT_SECRET` in `.env` is at least 32 characters.
+
+## Stopping the Server
+
+```bash
+# If running with cargo
+Ctrl+C
+
+# If running with Docker Compose
+docker compose down
+
+# Stop MongoDB (Docker)
+docker stop normogen-mongo
+docker rm normogen-mongo
+```
