-PowerShell support for host resize is coming soon.
+When using Powershell, the resize feature is referred to as a host 'Update'. Use the following commands to update the host:
+
+```azurepowershell-interactive
+Update-AzHost
+      [-ResourceGroupName] <String>
+      [-HostGroupName] <String>
+      [-Name] <String>
+      [-Sku <String>]
+      [-AutoReplaceOnFailure <Boolean>]
+      [-LicenseType <DedicatedHostLicenseTypes>]
+      [-DefaultProfile <IAzureContextContainer>]
+      [-WhatIf]
+      [-Confirm]
+      [<CommonParameters>]
+```
+
