+Terraform modules to automate the deployment of Kubecost in AWS and 
+integrate it with your EKS clusters:
+
+1. _aws-kubecost-iam_ (`aws-kubecost-iam/`) is a Terraform module 
+configuring IAM for each EKS cluster.
+2. _aws-kubecost-athena_ (`aws-kubecost-athena/`) is a Terraform module 
+creating AWS resources: buckets, CUR (Cost and Usage Report), Spot feed,
+and Athena.
+
+They are accompanied by an example of values for the [official Helm chart](https://docs.kubecost.com/install-and-configure/install/helm-install-params)
+to deploy Kubecost (`kubecost-helm-values.yaml`).
+
+This code is used (and better described) in the following article:
+* [“Kubecost with AWS integration: Implementing and automating with Terraform”](https://blog.palark.com/kubecost-aws-terraform-automation/)
