 1. wrap a configfile inside a configmap, and use `{{ .secretKey }}` as placeholder
 
-  ```yaml
-  ...
-  data:
-    index.html: |-
-      <h1>{{ .headline }}</h1>
-  ...
-  ```
+    ```yaml
+    ...
+    data:
+      index.html: |-
+        <h1>{{ .headline }}</h1>
+    ...
+    ```
 
 2. provide secrets inside Kubernetes Secrets
 
-  ```yaml
-  ...
-  data:
-    secret-headline: dmFsdWVGcm9tU2VjcmV0
-  ...
-  ```
+    ```yaml
+    ...
+    data:
+      secret-headline: dmFsdWVGcm9tU2VjcmV0
+    ...
+    ```
 
 3. configure an init-container using `k8s-multi-secret-to-file`, e.g.
 
-  ```yaml
-  ...
-  initContainers:
-    image: ghcr.io/spreadshirt/k8s-multi-secret-to-file:latest
-    imagePullPolicy: Always
-    name: secret-init
-    volumeMounts:
-      - mountPath: /etc/rendered
-        name: init-share
-      - mountPath: /etc/templates/index.html
-        name: configmap
-        subPath: index.html
-  ...
-  ```
+    ```yaml
+    ...
+    initContainers:
+      image: ghcr.io/spreadshirt/k8s-multi-secret-to-file:latest
+      imagePullPolicy: Always
+      name: secret-init
+      volumeMounts:
+        - mountPath: /etc/rendered
+          name: init-share
+        - mountPath: /etc/templates/index.html
+          name: configmap
+          subPath: index.html
+    ...
+    ```
 
 4. provide secrets as environment variables to the init container. Envs must be prefixed (default: `SECRET_`)
 
-  ```yaml
-  ...
-  - env:
-    - name: SECRET_headline
-      valueFrom:
-        secretKeyRef:
-          name: apache-demo
-          key: secret-headline
-  ...
-  ```
+    ```yaml
+    ...
+    - env:
+      - name: SECRET_headline
+        valueFrom:
+          secretKeyRef:
+            name: apache-demo
+            key: secret-headline
+    ...
+    ```
 
 5. configure [Volumes](https://kubernetes.io/docs/concepts/storage/volumes/) to allow interaction between the init-container and the application
 
-  ```yaml
-  ...
-  volumes:
-  - emptyDir: { }
-    name: init-share
-  - configMap:
-      name: apache-demo-cfg
-    name: configmap
-  ...
-  ```
+    ```yaml
+    ...
+    volumes:
+    - emptyDir: { }
+      name: init-share
+    - configMap:
+        name: apache-demo-cfg
+      name: configmap
+    ...
+    ```
 
 6. mount configfile and target path to init-container (IMPORTANT: don't mount the configfile directly to the application container!)
 
-  ```yaml
-  ...
-  volumeMounts:
-    - mountPath: /etc/rendered
-      name: init-share
-    - mountPath: /etc/templates/index.html
-      name: configmap
-      subPath: index.html
-  ...
-  ```
+    ```yaml
+    ...
+    volumeMounts:
+      - mountPath: /etc/rendered
+        name: init-share
+      - mountPath: /etc/templates/index.html
+        name: configmap
+        subPath: index.html
+    ...
+    ```
 
-`/etc/templates` and `/etc/rendered` are the default paths for templates and the results, this can be configured, if necessary

 7. mount the rendered config file to the application container
 
-  ```yaml
-  ...
-  volumeMounts:
-  - mountPath: /var/www/html/index.html
-    name: init-share
-    subPath: index.html
-  ...
-  ```
+    ```yaml
+    ...
+    volumeMounts:
+    - mountPath: /var/www/html/index.html
+      name: init-share
+      subPath: index.html
+    ...
+    ```
 
 8. deploy the application and check the rendered file inside the application container 
 
-  ```sh
-  $ kubectl exec <POD_NAME> -c apache -- cat /var/www/html/index.html
-  <h1>valueFromSecret</h1>
-  ```
+    ```sh
+    $ kubectl exec <POD_NAME> -c apache -- cat /var/www/html/index.html
+    <h1>valueFromSecret</h1>
+    ```
