 ### Create virtual machine in VirtualBox 
 
-The first thing we are going to do is create a new folder called virtualbox, we can then create a virtualbox.tf file and this is going to be where we define our resources. 
+The first thing we are going to do is create a new folder called virtualbox, we can then create a virtualbox.tf file and this is going to be where we define our resources. The code below which can be found in the VirtualBox folder as virtualbox.tf this is going to create 2 VMs in Virtualbox.

 Now that we have our code defined we can now perform the `terraform init` on our folder to download the provider for virtualbox.

-### Change configuration so that it then becomes a web server 
+### Change configuration 
 
+Lets add another node to our deployment. We can simply change the count line to show our newly desired number of nodes. When we run our `terraform apply` it will look something like below.

-### Add additional virtual machine to change our desired state 
+Once complete in virtualbox you can see we now have 3 nodes up and running.

+When we are finished we can clear this up using the `terraform destroy` and our machines will be removed.
