+# Demo Workflow - Build Up & Tear Down
+
+Perfect for demos that get built up and torn down frequently!
+
+## 🚀 Deploy (One Command)
+
+```bash
+cd /Users/phagen/GIT/opentelemetry-demo-Splunk
+kubectl apply -f kubernetes/opentelemetry-demo.yaml
+```
+
+Wait ~3 minutes for everything to initialize.
+
+## 🧹 Tear Down (One Command)
+
+```bash
+./cleanup.sh
+```
+
+This script:
+- ✅ Deletes all deployments, services, statefulsets
+- ✅ Cleans up all PVCs (prevents corrupted data)
+- ✅ Ensures fresh start on next deploy
+
+## What's Configured for Easy Demos
+
+### SQL Server StatefulSet
+**Added automatic PVC cleanup:**
+```yaml
+persistentVolumeClaimRetentionPolicy:
+  whenDeleted: Delete    # Auto-delete PVC when StatefulSet deleted
+  whenScaled: Delete     # Auto-delete PVC when scaled down
+```
+
+This means:
+- `kubectl delete` will automatically remove the PVC
+- No corrupted SQL Server data on next deploy
+- Clean slate every time
+
+### Fraud Detection Service
+**Auto-initializes everything:**
+- Creates `FraudDetection` database if missing
+- Creates `OrderLogs` table if missing
+- Logs every Kafka order message
+
+## Complete Demo Cycle
+
+### 1. Deploy
+```bash
+kubectl apply -f kubernetes/opentelemetry-demo.yaml
+```
+
+### 2. Verify
+```bash
+# Check pods are running
+kubectl get pods -n otel-demo
+kubectl get pods -n sql
+
+# Watch fraud-detection logs
+kubectl logs -f -n otel-demo -l app.kubernetes.io/component=fraud-detection
+```
+
+### 3. Use the Demo
+```bash
+# Access frontend
+kubectl port-forward -n otel-demo svc/frontend 8080:8080
+# Browse to http://localhost:8080 and place orders
+
+# Access SQL Server
+kubectl port-forward -n sql svc/sql-express 1433:1433
+# Connect to localhost:1433 with sa/ChangeMe_SuperStrong123!
+```
+
+### 4. Query Data
+```bash
+kubectl exec -it sql-express-0 -n sql -- /opt/mssql-tools/bin/sqlcmd -S localhost -U sa -P 'ChangeMe_SuperStrong123!' -Q "SELECT COUNT(*) FROM FraudDetection.dbo.OrderLogs"
+```
+
+### 5. Tear Down
+```bash
+./cleanup.sh
+```
+
+## Troubleshooting
+
+### SQL Server in CrashLoopBackOff
+
+**Cause:** Corrupted PVC from previous deployment
+
+**Fix:**
+```bash
+kubectl delete statefulset sql-express -n sql
+kubectl delete pvc data-sql-express-0 -n sql
+kubectl apply -f kubernetes/opentelemetry-demo.yaml
+```
+
+### Fraud Detection Stuck "waiting for sql-express"
+
+**Cause:** SQL Server not ready
+
+**Fix:**
+```bash
+# Check SQL Server status
+kubectl get pods -n sql
+kubectl logs sql-express-0 -n sql
+
+# If SQL Server is crashing, clean and redeploy
+./cleanup.sh
+kubectl apply -f kubernetes/opentelemetry-demo.yaml
+```
+
+## Files Modified for Demo Workflow
+
+### Changed
+- `kubernetes/opentelemetry-demo.yaml`
+  - Line 343-345: Added `persistentVolumeClaimRetentionPolicy` to sql-express StatefulSet
+  - Line 1372: Updated fraud-detection image to `2.1.3-sql.1`
+  - Line 1402-1411: Added SQL Server environment variables
+  - Line 1423-1428: Added wait-for-sqlserver init container
+
+### Added
+- `cleanup.sh` - Automated cleanup script
+- `src/fraud-detection/build-fraud-detection.sh` - Build script
+- All fraud-detection code for SQL Server logging
+
