   1. Create a file named `my-drupal-site.yml` with the following contents:
 
-         ```
-         ---
-         apiVersion: drupal.drupal.org/v1alpha1
-         kind: Drupal
-         metadata:
-           name: my-drupal-site

-         spec:
-           drupal_image: 'drupal:8.7-apache'
-           # You should generate your own hash salt, e.g. `Crypt::randomBytesBase64(55)`.
-           drupal_hash_salt: 'provide hash_salt here'

   2. Use `kubectl` to create the Drupal site in your cluster:
 
-         ```
-         kubectl apply -f my-drupal-site.yml
-         ```
+     ```
+     kubectl apply -f my-drupal-site.yml

 > You can also deploy `Drupal` applications into other namespaces by changing `metadata.namespace`, or deploy multiple `Drupal` instances into the same namespace by changing `metadata.name`.
