+## To workaround
+### check the current configurations
+cat /etc/resolv.conf
+
+### create the /etc/wsl.conf file to disable /etc/resolv.conf generation
+printf "[network]\ngenerateResolvConf = false" >> /etc/wsl.conf
+
+### remove the symlink WSL2 created
+rm /etc/resolv.conf
+
+### finally, add your public DNS server to the /etc/resolv.conf file. If your VPN server has a nameserver, add it too
+echo "nameserver 8.8.8.8" >> /etc/resolv.conf
+echo "nameserver 1.1.1.1" >> /etc/resolv.conf
+
+>Note: the /etc/resolv.conf file gets removed at each reboot

+# Terraform Azure Eventhub Example
+
+This folder contains a simple Terraform module that deploys resources in [Azure](https://azure.microsoft.com/) to demonstrate
+how you can use Terratest to write automated tests for your Azure Terraform code. This module deploys an [Azure Event Hubs](https://azure.microsoft.com/en-us/products/event-hubs/).
+
+Check out [test/azure/terraform_azure_eventhub_example_test.go](/test/azure/terraform_azure_eventhub_example_test.go) to see how you can write automated tests for this module.
+
+Note that the resources deployed in this module don't actually do anything; it just runs the resources for demonstration purposes.
+
+**WARNING**: This module and the automated tests for it deploy real resources into your Azure account which can cost you money. The resources are all part of the [Azure Free Account](https://azure.microsoft.com/free/), so if you haven't used that up, it should be free, but you are completely responsible for all Azure charges.
+
+## Running this module manually
+
+1. Sign up for [Azure](https://azure.microsoft.com/)
+1. Configure your Azure credentials using one of the [supported methods for Azure CLI
+   tools](https://docs.microsoft.com/cli/azure/azure-cli-configuration?view=azure-cli-latest)
+1. Install [Terraform](https://www.terraform.io/) and make sure it's on your `PATH`
+1. Ensure [environment variables](../README.md#review-environment-variables) are available
+1. Run `terraform init`
+1. Run `terraform apply`
+1. When you're done, run `terraform destroy`
+
+## Running automated tests against this module
+
+1. Sign up for [Azure](https://azure.microsoft.com/).
+2. Configure your Azure credentials using one of the [supported methods for Azure CLI tools](https://docs.microsoft.com/cli/azure/azure-cli-configuration?view=azure-cli-latest).
+
+3. Install [Terraform](https://www.terraform.io/) and make sure it's on your `PATH`.
+4. [Review environment variables](#review-environment-variables).
+5. Install [Golang](https://golang.org/) and make sure this code is checked out into your `GOPATH`.
+6. `cd test`
+7. Make sure [the azure-sdk-for-go versions match](#check-go-dependencies) in [/test/go.mod](/test/go.mod) and in [test/azure/terraform_azure_eventhub_example_test.go](/test/azure/terraform_azure_eventhub_example_test.go).
+8. `go test -v -run TestTerraformAzureEventhubkExample`
