+# Packer Template for Microsoft Windows
+
+## Introduction
+
+The Packer templates in this directory creates Windows Server images for use with MAAS.
+
+
+## Prerequisites (to create the image)
+
+* A machine running Ubuntu 18.04+ with the ability to run KVM virtual machines.
+* qemu-utils, libnbd-bin, nbdkit and fuse2fs
+* qemu-system
+* ovmf
+* cloud-image-utils
+* [Packer](https://www.packer.io/intro/getting-started/install.html), v1.7.0 or newer
+
+
+## Requirements (to deploy the image)
+
+* [MAAS](https://maas.io) 3.2+
+* [Curtin](https://launchpad.net/curtin) 21.0+
+
+
+## Supported Microsoft Windows Versions
+
+This process has been build and deployment tested with the following versions of
+Microsoft Windows:
+
+* Windows Server 2022
+* Windows Server 2019
+* Windows Server 2016
+* Windows 10 Pro 22H2
+
+
+## Known Issues
+
+* The current process builds UEFI compatible images only.
+
+
+## windows.json Template
+
+This template builds a dd.tgz MAAS image from an official Microsoft Windows ISO. 
+This process also installs the latest VirtIO drivers as well as Cloudbase-init.
+
+
+## Obtaining Microsoft Windows ISO images
+
+You can obtains Microsoft Windows Evaluation ISO images from the following links:
+
+* [Windows Server 2022](https://www.microsoft.com/en-us/evalcenter/download-windows-server-2022)
+* [Windows Server 2019](https://www.microsoft.com/en-us/evalcenter/download-windows-server-2019)
+* [Windows Server 2016](https://www.microsoft.com/en-us/evalcenter/download-windows-server-2016)
+
+
+### Building the image
+
+The build the image you give the template a script which has all the
+customization:
+
+```shell
+sudo make windows ISO=<path-to-iso> VERSION=<windows-version> windows.json
+```
+
+### Makefile Parameters
+
+#### BOOT
+
+Currently uefi is the only supported value.
+
+#### EDIT
+
+The edition of a targeted ISO image. It defaults to PRO for Microsoft Windows 10/11
+and SERVERSTANDARD for Microsoft Windows Servers. Many Microsoft Windows Server ISO
+images do contain multiple editions and this prarameter is useful to build a particular
+edition such as Standard or Datacenter etc.
+
+#### ISO
+
+Path to Microsoft Windows ISO used to build the image.
+
+#### PACKER_LOG
+
+Enable (1) or Disable (0) verbose packer logs. The default value is set to 0.
+
+#### PKEY
+
+User supplied Microsoft Windows Product Key. When usimg KMS, you can obtain the
+activation keys from the link below:
+
+* [KMS Client Activation and Product Keys](https://learn.microsoft.com/en-us/windows-server/get-started/kms-client-activation-keys)
+
+Please note that PKEY is an optional parameter but it might be required during
+the build time depending on the type of ISO being used. Evaluation series ISO
+images usually do not require a product key to proceed, however this is not
+true with Enterprise and Retail ISO images.
+
+#### VERSION
+
+Specify the Microsoft Windows Version. Example inputs include: 2022, 2019, 2016
+and 10.
+
+
+## Uploading images to MAAS
+
+Use MAAS CLI to upload the image:
+
+```shell
+maas admin boot-resources create \
+    name='windows/windows-server' \
+    title='Windows Server' \
+    architecture='amd64/generic' \
+    filetype='ddtgz' \
+    content@=windows-server-amd64-root-dd.gz
+```
