 ```
 
 2. Create cluster
-```
+All commands will be applied via Terraform 1.7.0 and via OpenTofu, the same version.
-terraform init

+tofu output
 ```
-gcloud container clusters get-credentials $(terraform output -raw kubernetes_cluster_name) --region $(terraform output -raw region) --project $(terraform output -raw project)
+
+There is a manual command:
+```bash
+gcloud container clusters get-credentials $(tofu output -raw kubernetes_cluster_name) --region $(tofu output -raw region) --project $(tofu output -raw project)

 4. Destroy all resources
-```
-terraform destroy -target 'kubernetes_namespace.flux-system'
-terraform destroy -target 'google_container_node_pool.primary_nodes'
-terraform destroy -target 'google_container_cluster.primary'
-terraform destroy -target 'google_compute_subnetwork.subnet'
-terraform destroy -target 'google_compute_network.vpc'
-terraform destroy -target 'data.google_client_config.primary'
