+## Install Terraform
+
+1. Install Terraform if it is not already installed (visit [terraform.io](https://terraform.io) for other distributions):
+
+```
+./terraform-install.sh
+```
+
+## Change to the example directory
+
+```
+cd example-gke-k8s-multi-region/
+```
+
 ## Set up the environment
 
+1. Set the project, replace `YOUR_PROJECT` with your project ID:
+
 ```
-gcloud auth application-default login
+PROJECT=YOUR_PROJECT
+```
+
+```
+gcloud config set project ${PROJECT}
+```
+
+2. Configure the environment for Terraform:
+
+```
+[[ $CLOUD_SHELL ]] || gcloud auth application-default login
 export GOOGLE_PROJECT=$(gcloud config get-value project)
 ```
 
 ## Run Terraform
 
 ```
 terraform init
-terraform plan
 terraform apply
 ```
 
 ## Testing
 
-Open the address of the load balancer in a browser once it is ready:
+1. Wait for the load balancer to be provisioned:
+
+```
+./test.sh
+```
+
+2. Open the address of the load balancer:
 
 ```
-(until curl --connect-timeout 1 -sf -o /dev/null http://$(terraform output load-balancer-ip); do echo "Waiting for Load Balancer... "; sleep 5 ; done) && open http://$(terraform output load-balancer-ip)
+echo http://$(terraform output load-balancer-ip)
 ```
 
 ## Cleanup
 
+1. Delete resources created by terraform:
+
 ```
 terraform destroy
 ```
