 ### Kubernetes with Helm
 
-1. Build and push Docker image:
+**Quick Start:**
 ```bash
-docker build -t your-registry/datalake:latest .
-docker push your-registry/datalake:latest
+helm install warehouse13 ./helm/warehouse13 --namespace warehouse13 --create-namespace
 ```
 
-2. Install with Helm:
+**Production Deployment:**
 ```bash
-helm install datalake ./helm \
-  --set image.repository=your-registry/datalake \
-  --set image.tag=latest \
-  --namespace datalake \
-  --create-namespace
+helm install warehouse13 ./helm/warehouse13 \
+  --namespace warehouse13 \
+  --create-namespace \
+  --values ./helm/warehouse13/values-production.yaml
 ```
 
-3. Access the API:
+**Air-Gapped Deployment:**
 ```bash
-kubectl port-forward -n datalake svc/datalake 8000:8000
+helm install warehouse13 ./helm/warehouse13 \
+  --namespace warehouse13 \
+  --create-namespace \
+  --values ./helm/warehouse13/values-airgapped.yaml
 ```
 
+**Access the Application:**
+```bash
+kubectl port-forward -n warehouse13 svc/warehouse13-frontend 4200:80
