-# Azure Kubernetes Service (AKS) Terraform Example
+# azure-aks-k8s
 
-This example demonstrates how to deploy an Azure Kubernetes Service (AKS) cluster using Terraform. The configuration includes:
+This example creates the following:
 
-- Resource Group
-- Virtual Network and Subnet
-- AKS Cluster with default node pool
-- System-assigned managed identity
-- Azure CNI networking
+- a Virtual Network with appropriate subnets using the [Azure RM Module for Network](https://registry.terraform.io/modules/Azure/network/azurerm/latest)
+from the Terraform Registry
+- an Azure Kubernetes Service (AKS) cluster with default node pool
+- a system-assigned managed identity for the AKS cluster
+- Azure CNI networking for better network performance
+- Optional Log Analytics workspace for monitoring
 
 ## Prerequisites
 
-1. [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli) installed
-2. [Terraform](https://www.terraform.io/downloads.html) installed (version >= 1.0)
-3. Azure subscription and appropriate permissions
+- [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli) installed
+- [Terraform](https://www.terraform.io/downloads.html) installed (version >= 1.0)
+- Azure subscription and appropriate permissions
 
-## Authentication
+## To use
 
-Before running Terraform, you need to authenticate with Azure. You can do this by running:
+Follow the documentation to configure the Azure provider:
 
-```bash
-az login
-```
+- [Azure](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs)
 
-## Usage
+### Deploy
 
-1. Initialize Terraform:
-```bash
+```shell
 terraform init
-```
-
-2. Review the planned changes:
-```bash
-terraform plan
-```
-
-3. Apply the configuration:
-```bash
 terraform apply
 ```
 
-4. To destroy the infrastructure:
-```bash
+## To destroy
+
+```shell
 terraform destroy
 ```
