-`$mkdir terraform-first-instance`
+- `$mkdir terraform-first-instance`
 
-Install Terraform:
+### Install Terraform:
 
-`$brew install terraform`
+- `$brew install terraform`
 
-Unzip the file and make a path to your new directory:
+### Unzip the file and make a path to your new directory using:

-Create a new application credintial in Openstack:
+### Create a new application credintial in Openstack:
 
-In Openstack, go to Identity - Application Credentials
+- In Openstack, go to **Identity** -> **Application Credentials**
 
-Click "Create Application Credential"
+- Click "**Create Application Credential**"
 
-Name the credential and add a description(Leave the rest blank. It is important not to add an expiration date.)
+- Name the credential, add a description, and check the box making it unrestricted (Leave the rest blank. It is important not to add an expiration date.)
 
-Open the credential rc file you have created, and change all OS_ to TF_. This will allow terraform to read and use these values.
+- Download the credentials as an RC file.
 
-Save the credential in your terraform-first-instance directory.
+- Edit variables in credentials RC file to TF_ from OS_. Everything else stays the same.
 
-Download RC File from Openstack(V3) and save it in your terraform-first-instance directory.
+- Save credentials RC file in your terraform-first-instance directory.
 
-Clone this repo into your terraform-first-instance directory:
 
-`$git clone --recursive https://gitlab.rc.uab.edu/rrand11/terraform-openstack.git`
+### Clone this repo into your terraform-first-instance directory using:
 
-Source the openrc file and enter your password for openstack (you will only need to do this the very first time):
+- `$git clone --recursive https://gitlab.rc.uab.edu/rrand11/terraform-openstack.git`

-Write Terraform Plan to your terraform-first-instance directory and run that plan:
+- `$terraform plan -out $HOME/terraform-first-instance/terraform-plan.tf`
 
-`$terraform plan -out $HOME/terraform-first-instance/terraform-plan.tf`
+**_(Note)_** `$terraform plan -out` writes the plan to a file and then `terraform apply` runs that plan.
