+# BOSH Windows Stemcell Builder
 
 This repository contains Rake tasks for creating BOSH Windows stemcells for AWS, Azure, GCP, and Openstack
 
 The recommended approach for creating BOSH Windows stemcells for vSphere which can be deployed on [Cloud Foundry BOSH](https://bosh.io), is [`stembuild`](https://github.com/cloudfoundry/stembuild).
 
 [Documentation on how to use `stembuild` can be found here.](https://bosh.io/docs/windows-stemcell-create/)
