 In this article, you learn how to use Azure VM Image Builder and the Azure CLI to create an image version in an [Azure Compute Gallery](../shared-image-galleries.md) (formerly Shared Image Gallery) and then distribute the image globally. You can also create an image version by using [Azure PowerShell](../windows/image-builder-gallery.md).
 
-
 This article uses a sample JSON template to configure the image. The JSON file is at [helloImageTemplateforSIG.json](https://github.com/danielsollondon/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.

 VM Image Builder uses the provided [user-identity](../../active-directory/managed-identities-azure-resources/qs-configure-cli-windows-vm.md#user-assigned-managed-identity) to inject the image into an Azure Compute Gallery. In this example, you create an Azure role definition with specific actions for distributing the image. The role definition is then assigned to the user identity.
