+### Create a namespace
+
+```yaml
+# 01-namespace.yaml
+apiVersion: v1
+kind: Namespace
+metadata:
+  name: wg-easy
+```
+
+### Create a PVC
+
+```yaml
+# 02-pvc.yaml
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: wg-config
+  namespace: wg-easy
+spec:
+  accessModes:
+    - ReadWriteOnce
+  storageClassName: local-path
+  resources:
+    requests:
+      storage: 100Mi
+```
+
+
+### Create the deployment
+
+Note this example uses a host port. You could create a node port instead as well. Ensure that `INIT_PORT`, `containerPort` and `hostPort` coincide.  
+
+The below is an example; please refer to [_Optional config_][docs-optional-config] and [_Unattended setup_][docs-unattended-setup] for all possible variables.

+        - name: config
+          persistentVolumeClaim:

+
+### Create a service
+```yaml
+# 04-service.yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: wg-easy-http
+  namespace: wg-easy
+spec:
+  ports:
+    - name: http
+      port: 51821
+      protocol: TCP
+      targetPort: http
+  selector:
+    app.kubernetes.io/name: wg-easy
+  type: ClusterIP
+  ``` 
+
+### (optional) Create an ingress
+
+For example, using `traefik` ingress class
+
+```yaml
+# 05-ingress.yaml
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+  name: wg-easy
+  namespace: wg-easy
+spec:
+  ingressClassName: traefik
+  rules:
+    - host: wg.yourdomain.com
+      http:
+        paths:
+          - backend:
+              service:
+                name: wg-easy-http
+                port:
+                  name: http
+            path: /
+            pathType: Prefix
+```
+
+You should now be able to browse https://wg.yourdomain.com and set up your wireguard config.
