-When a user in a host pool accesses MSIX images, they must be stored in a network share with read-only permissions. In the how-to, you'll learn the steps needed to set up a file share for MSIX app attach.
+For a user to access MSIX images, the images must be stored on a network share. In this article, you'll learn how to set up a file share for MSIX app attach.
 
 MSIX app attach doesn't have dependencies on the type of storage fabric the file share uses. The considerations for the MSIX app attach share are same as the considerations for an FSLogix share. To learn more about storage requirements, see [Storage options for FSLogix profile containers in Azure Virtual Desktop](store-fslogix-profile.md).

 - Separate the storage fabrics for MSIX app attach from FSLogix profile containers.
 - Any disaster recovery plans for Azure Virtual Desktop must include replicating the MSIX app attach file share in your secondary failover location. To learn more about disaster recovery, see [Set up a business continuity and disaster recovery plan](disaster-recovery.md). You'll also need to ensure your file share path is accessible in the secondary location. You can use [Distributed File System (DFS) Namespaces](/windows-server/storage/dfs-namespaces/dfs-overview) to provide a single share name across different file shares.
