 1. Use the `New-AzResourceGroup` command to create a resource group:
 
     ```azurepowershell
-    New-AzResourceGroup -Name <resource-group> -Location eastus
+    New-AzResourceGroup -Name "<resource-group>" -Location "eastus"
     ```
 
     You can change "eastus" to a location nearer to you, if you prefer.
 
 1. Use `New-AzKeyVault` to create the key vault:
 
     ```azurepowershell
-    New-AzKeyVault -Name <vault-name> -ResourceGroupName <resource-group> -Location eastus -EnableRbacAuthorization $true -EnablePurgeProtection
+    New-AzKeyVault -Name "<vault-name>" -ResourceGroupName "<resource-group>" -Location "eastus" -EnableRbacAuthorization $true -EnablePurgeProtection
     ```
 
     Replace `<vault-name>` with a name that's unique across all of Azure. You typically use your personal or company name along with other numbers and identifiers.
