+
+Provision Azure infrastructure with Terraform.
+
+## Provider Configuration
+
+```hcl
+terraform {
+  required_providers {
+    azurerm = {
+      source  = "hashicorp/azurerm"
+      version = "~> 3.0"
+    }
+  }
+  backend "azurerm" {
+    resource_group_name  = "tfstate"
+    storage_account_name = "tfstate12345"
+    container_name       = "tfstate"
+    key                  = "prod.terraform.tfstate"
+  }
+}
+
+provider "azurerm" {
+  features {}
+}
+```
+
+## Example Resources
+
+```hcl
+resource "azurerm_resource_group" "main" {
+  name     = "myapp-rg"
+  location = "East US"
+}
+
+resource "azurerm_virtual_network" "main" {
+  name                = "myapp-vnet"
+  address_space       = ["10.0.0.0/16"]
+  location            = azurerm_resource_group.main.location
+  resource_group_name = azurerm_resource_group.main.name
+}
+```
+
+## Best Practices
+
+- Use remote state in Azure Storage
+- Implement resource naming conventions
+- Use data sources for existing resources
+- Tag all resources
+- Use modules for reusability
