-Terraform-aws-csit modules
---------------------------
+AWS Deployments
+---------------
-Terraform-aws-csit module is IaaC - infrastructure as a code. Module uses the
-Amazon Web Services (AWS) provider to interact with resources provided by AWS
-to orchestrate virtual environment for running CSIT tests.

-- `aws `_.
+CSIT performance testbed deployments in AWS rely on
+Infrastructure-as-a-C (IaaC) Terraform AWS providers. Terraform
+providers specified in CSIT interact with resources provided by AWS to
+orchestrate virtual environment for running CSIT performance tests. For
