 Terraform reads **app_map.tfvars** to know which application will be installed on Rancher
 and which version and customized values need to apply to.
 
-Here is the example of **app_map.tfvars** which is used to install the **hostpath** storage.
-We specify the Helm Chart version to **0.2.9** and use the file **hostpath.yaml** as the custom values
+Here is the example of **app_map.tfvars** which defines prerequisite apps for TOST
+as well as project and namespace in which TOST apps will be provisioned.
+Note that currently we don't have any prerequisite so we left this blank intentionally.
+It can be used to specify prerequisites in the future.

 ONOS folder
 ^^^^^^^^^^^

+The **app_map.tfvars** in this folder describes the information about ONOS helm chart.
 
 In this example, we specify the **onos-tost** helm chart version to **0.1.18** and load **onos.yaml**
