+## 📦 WHAT GETS BUILT
+
+### Backend Container (Dockerfile.backend)
+
+```dockerfile
+FROM oven/bun:latest as builder
+  ↓ Installs dependencies
+COPY Mode3Test/backend ./backend
+COPY package.json, bunfig.toml
+RUN bun install --production
+
+FROM oven/bun:latest (Runtime stage)
+  ↓ Minimal final image
+COPY from builder
+ENV NODE_ENV=production
+ENV PORT=3005
+HEALTHCHECK /health
+EXPOSE 3005
+CMD ["bun", "run", "dev"]
+```
+
+**Result**: Optimized Bun container with OAuth2 backend
+
+### Frontend Container (Dockerfile.frontend)
+
+```dockerfile
+FROM node:18-alpine as builder
+  ↓ Build production bundle
+COPY frontend/
+RUN npm ci
+RUN npm run build
+
+FROM node:18-alpine (Runtime stage)
+  ↓ Lightweight static server
+COPY --from=builder /app/dist ./dist
+RUN npm install -g serve
+HEALTHCHECK /
+EXPOSE 5173
+CMD ["serve", "-s", "dist", "-l", "5173"]
+```
+
+**Result**: Production-optimized frontend container (42.70 kB gzip!)

+
+## ✅ HEALTH CHECKS
+
+### Backend Health Check
+```bash
+# Every 30 seconds, Docker runs:
+curl -f http://localhost:3005/health
+
+# Expected response: 200 OK
+# If fails 3 times: Container marked unhealthy
+```
+
+### Frontend Health Check
+```bash
+# Every 30 seconds, Docker runs:
+wget --quiet --tries=1 --spider http://localhost:5173
+
+# Expected: HTTP 200
+# If fails 3 times: Container marked unhealthy
+```
+
+---
+
+## 🔒 SECURITY FEATURES
+
+### Network Isolation
+```
+job-info-network (bridge)
+├─ Backend (only accessible via network)
+└─ Frontend (accessible from network)
+
+→ No external access without port mapping
+→ Containers communicate securely
+→ Network policies can be enforced
+```
+
+### Environment Variables
+```
+✓ OAuth credentials via env vars (not in code)
+✓ Production mode enforced
+✓ Log level configurable
+✓ Secrets not exposed in image
+```
+
+### Container Restart
+```
+Policy: unless-stopped
+→ Automatically restart if container crashes
+→ Preserves data across restarts
+→ Supports graceful shutdown
+```
+
+---
+

+# Removes containers, network, and volumes
+# Full reset for fresh start
+```
+
+---
+
+## 🎯 WHAT TO EXPECT
+
+### First Run
+```
+Time: ~2-3 minutes (builds images)
+Output: 
+  ✓ Building backend image
+  ✓ Building frontend image
+  ✓ Starting containers
+  ✓ Waiting for health checks
+  ✓ Both services ready
+```
+
+### Subsequent Runs
+```
+Time: ~30 seconds
+Output:
+  ✓ Containers start immediately
+  ✓ Health checks pass
+  ✓ Services ready
+```
+
+### Application Ready
+```
+✓ Backend: http://localhost:3005 (healthy)
+✓ Frontend: http://localhost:5173 (healthy)

+
+## 🔧 COMMON COMMANDS
+
+```bash
+# Build and start
+docker-compose up -d

+# Stop
+docker-compose stop
+
+# Restart
+docker-compose restart
+
+# Full cleanup

+
+## 📚 WHAT'S INCLUDED
+
+- ✅ Multi-stage Docker builds (optimized images)
+- ✅ Health checks (automated monitoring)
+- ✅ Dependency management (backend waits for healthy)
+- ✅ Network isolation (secure communication)
+- ✅ Environment variables (configurable)
+- ✅ Volume mounts (source code binding)
+- ✅ Restart policies (automatic recovery)
+- ✅ Port mapping (accessible from host)
+
+---
+
+## 🎉 BOTTOM LINE
+
+When you run `docker-compose up -d`:
+
+1. **Two optimized containers start** (backend + frontend)
+2. **Network connects them securely** (job-info-network)
+3. **Health checks monitor both** (auto-restart if needed)
+4. **Frontend waits for backend** (depends_on)
+5. **Everything is ready in 2-3 minutes** (first run)
+
+Then you can:
+- Open http://localhost:5173 in browser
+- Click "Sign In with Microsoft"
+- See the full production application
+- Experience all features (caching, offline, etc.)
+
+**All infrastructure & dependencies are fully automated!**
