   - `id` - (Required) The UUID of the private network resource.

 ~> **Important:** The way to use private networks differs whether you are using redis in standalone or cluster mode.
+
 - Standalone mode (`cluster_size` = 1) : you can attach as many private networks as you want (each must be a separate block). If you detach your only private network, your cluster won't be reachable until you define a new private or public network. You can modify your private_network and its specs, you can have both a private and public network side by side.
+
 - Cluster mode (`cluster_size` > 1) : you can define a single private network as you create your cluster, you won't be able to edit or detach it afterwards, unless you create another cluster. Your `service_ips` must be listed as follows:
+
 ```hcl
   service_ips = [
-    "10.12.1.10/20", 
+    "10.12.1.10/20",
     "10.12.1.11/20",
