+description: Learn Terraform Commands like init, validate, plan, apply and destroy
+---
+
+## Step-01: Introduction
+- Understand basic Terraform Commands
+1. terraform init
+2. terraform validate
+3. terraform plan
+4. terraform apply
+5. terraform destroy      
+

+
+## Step-02: Review terraform manifests
+- **Pre-Conditions-1:** Get Azure Regions and decide the region where you want to create resources
+```t
+# Get Azure Regions
+az account list-locations -o table
+```
+- **Pre-Conditions-2:** If not done earlier, complete `az login` via Azure CLI. We are going to use Azure CLI Authentication for Terraform when we use Terraform Commands. 
+```t
+# Azure CLI Login
+az login
+
+# List Subscriptions
+az account list
+
+# Set Specific Subscription (if we have multiple subscriptions)
+az account set --subscription="SUBSCRIPTION_ID"
+```
+- [Azure Regions](https://docs.microsoft.com/en-us/azure/virtual-machines/regions)
+- [Azure Regions Detailed](https://docs.microsoft.com/en-us/azure/best-practices-availability-paired-regions#what-are-paired-regions)
+```t
+# Terraform Settings Block
+terraform {
+  required_version = ">= 1.0.0"
+  required_providers {
+    azurerm = {
+      source = "hashicorp/azurerm"
+      version = ">= 2.0" # Optional but recommended in production
+    }    
+  }
+}
+# Configure the Microsoft Azure Provider
+provider "azurerm" {
+  features {}
+}
+# Create Resource Group 
+resource "azurerm_resource_group" "my_demo_rg1" {
+  location = "eastus"
+  name = "my-demo-rg1"  
+}
+```
+
+## Step-03: Terraform Core Commands
+```t
+# Terraform Initialize
+terraform init
+
+# Terraform Validate
+terraform validate
+
+# Terraform Plan to Verify what it is going to create / update / destroy
+terraform plan
+
+# Terraform Apply to Create Resources
+terraform apply 
+```
+
+## Step-04: Verify Azure Resource Group in Azure Management Console
+- Go to Azure Management Console -> Resource Groups 
+- Verify newly created Resource Group
+- Review `terraform.tfstate` file 
+
+## Step-05: Destroy Infrastructure
+```t
+# Destroy Azure Resource Group 
+terraform destroy
+Observation:
+1. Verify if the resource group got deleted in Azure Management Console
+2. Verify terraform.tfstate file and resource group info should be removed
+3. Verify terraform.tfstate.backup, it should have the resource group info here stored as backup. 
+
+# Delete Terraform files 
+rm -rf .terraform*
+rm -rf terraform.tfstate*
+```
+
+## Step-08: Conclusion
+- Re-iterate what we have learned in this section
+- Learned about Important Terraform Commands
+1. terraform init
+2. terraform validate
+3. terraform plan
+4. terraform apply
+5. terraform destroy

+title: Terraform Configuration Language Syntax
+description: Learn Terraform Configuration Language Syntax like Blocks, Arguments, Comments etc
+---
+
+## Step-01: Introduction
+- Understand Terraform Language Basics
+1. Understand Blocks
+2. Understand Arguments, Attributes & Meta-Arguments
+3. Understand Identifiers
+4. Understand Comments
+
+
+## Step-02: Terraform Configuration Language Syntax
+- Understand Blocks
+- Understand Arguments
+- Understand Identifiers
+- Understand Comments
+- [Terraform Configuration](https://www.terraform.io/docs/configuration/index.html)
+- [Terraform Configuration Syntax](https://www.terraform.io/docs/configuration/syntax.html)
+```t
+# Template
+<BLOCK TYPE> "<BLOCK LABEL>" "<BLOCK LABEL>"   {
+  # Block body
+  <IDENTIFIER> = <EXPRESSION> # Argument
+}
+
+# Azure Example
+# Create a resource group
+resource "azurerm_resource_group" "myrg" { # Resource BLOCK
+  name = "myrg-1" # Argument
+  location = "East US" # Argument 
+}
+# Create Virtual Network
+resource "azurerm_virtual_network" "myvnet" { # Resource BLOCK
+  name                = "myvnet-1" # Argument
+  address_space       = ["10.0.0.0/16"]
+  location            = azurerm_resource_group.myrg.location # Argument with value as expression
+  resource_group_name = azurerm_resource_group.myrg.name # Argument with value as expression
+}
+```
+
+## Step-03: Understand about Arguments, Attributes and Meta-Arguments.
+- Arguments can be `required` or `optional`
+- Attribues format looks like `resource_type.resource_name.attribute_name`
+- Meta-Arguments change a resource type's behavior (Example: count, for_each)
