+### Option 4: Kubernetes with Helm
+
+For Kubernetes deployments, use the official Helm chart.
+
+**Step 1:** Clone the repository:
+
+```bash
+git clone https://github.com/RostislavDugin/postgresus.git
+cd postgresus
+```
+
+**Step 2:** Install with Helm:
+
+```bash
+helm install postgresus ./deploy/helm -n postgresus --create-namespace
+```
+
+**Step 3:** Get the external IP:
+
+```bash
+kubectl get svc -n postgresus
+```
+
+Access Postgresus at `http://<EXTERNAL-IP>` (port 80).
+
+To customize the installation (e.g., storage size, NodePort instead of LoadBalancer), see the [Helm chart README](deploy/helm/README.md) for all configuration options.
+
+Config uses by default LoadBalancer, but has predefined values for Ingress and HTTPRoute as well.

+## Examples
+
+### Basic Installation (LoadBalancer on port 80)
+
+Default installation exposes Postgresus via LoadBalancer on port 80:
+
+```bash
+helm install postgresus ./deploy/helm -n postgresus --create-namespace
+```
+
+Access via `http://<EXTERNAL-IP>`
+
+### Using NodePort
+
+If your cluster doesn't support LoadBalancer:
+
+```yaml
+# nodeport-values.yaml
+service:
+  type: NodePort
+  port: 80
+  targetPort: 4005
+  nodePort: 30080
+```
+
+```bash
+helm install postgresus ./deploy/helm -n postgresus --create-namespace -f nodeport-values.yaml
+```
+
+Access via `http://<NODE-IP>:30080`
+
+### Enable Ingress with HTTPS
+
+For domain-based access with TLS:
+
+```yaml
+# ingress-values.yaml
+service:
+  type: ClusterIP
+  port: 4005
+  targetPort: 4005
+
+ingress:
+  enabled: true
+  className: nginx
+  annotations:
+    nginx.ingress.kubernetes.io/ssl-redirect: "true"
+    cert-manager.io/cluster-issuer: "letsencrypt-prod"
+  hosts:
+    - host: backup.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+  tls:
+    - secretName: backup-example-com-tls
+      hosts:
+        - backup.example.com
+```
+
+```bash
+helm install postgresus ./deploy/helm -n postgresus --create-namespace -f ingress-values.yaml
+```
+
+### HTTPRoute (Gateway API)
+
+For clusters using Istio, Envoy Gateway, Cilium, or other Gateway API implementations:
+
+```yaml
+# httproute-values.yaml
+service:
+  type: ClusterIP
+
+route:
+  enabled: true
+  hostnames:
+    - backup.example.com
+  parentRefs:
+    - name: my-gateway
+      namespace: istio-system
+```
+
+```bash
+helm install postgresus ./deploy/helm -n postgresus --create-namespace -f httproute-values.yaml
+```
+
+### Custom Storage Size
+
+```yaml
+# storage-values.yaml
+persistence:
+  size: 50Gi
+  storageClassName: "fast-ssd"
+```
+
+```bash
+helm install postgresus ./deploy/helm -n postgresus --create-namespace -f storage-values.yaml
+```
