 This article shows you how you can use the Azure Image Builder, and the Azure CLI, to create an image version in an [Azure Compute Gallery](../shared-image-galleries.md) (formerly known as Shared Image Gallery), then distribute the image globally. You can also do this using [Azure PowerShell](../windows/image-builder-gallery.md).
 
-We will be using a sample .json template to configure the image. The .json file we are using is here: [helloImageTemplateforSIG.json](https://github.com/azure/azvmimagebuilder/blob/master/quickquickstarts/1_Creating_a_Custom_Linux_Shared_Image_Gallery_Image/helloImageTemplateforSIG.json).

 To distribute the image to an Azure Compute Gallery, the template uses [sharedImage](image-builder-json.md#distribute-sharedimage) as the value for the `distribute` section of the template.
