+# Get ready to preview new mixed reality apps for HoloLens
+
+Microsoft has just announced two new mixed reality apps coming to HoloLens: Microsoft Remote Assist and Microsoft Layout.
+
+On May 22, 2018, these apps will be available to download for free for a limited time from the [Microsoft Store](https://www.microsoft.com/en-us/store/apps) and [Microsoft Store for Business](https://businessstore.microsoft.com/en-us/store). At that time you'll be able to distribute the apps across your organization as part of a public preview. In the meantime, here's what you need to know to prepare for the public preview of each app, to make sure your roll-out is smooth and seamless.
+
+## Microsoft Remote Assist
+
+Microsoft Remote Assist enables collaboration in mixed reality to solve problems faster. Firstline workers can collaborate remotely with heads-up, hands-free video calling, image sharing, and mixed reality annotations. They can share what they see with an expert on Microsoft Teams, while staying hands-on to solve problems and complete tasks together, faster.
+
+Below, you'll find the technical requirements you'll need to meet in order to distribute Microsoft Remote Assist throughout your organization when it's available from the [Microsoft Store](https://www.microsoft.com/en-us/store/apps) and [Microsoft Store for Business](https://businessstore.microsoft.com/en-us/store) on May 22, 2018.
+
+### Device requirements
+
+| Device                     | OS requirements                   | Details                                                    |
+|:---------------------------|:----------------------------------|:-----------------------------------------------------------|
+| HoloLens                   | RS1, build 10.0.14393.0           | See [Manage updates to HoloLens](https://docs.microsoft.com/en-us/HoloLens/hololens-updates) for instructions on using Windows Update for Business, MDM, and Windows Server Update Service (WSUS) to deploy updates to HoloLens.   |
+| Windows 10 PC (optional)   | Any Windows 10 build              | You can use a Windows 10 PC to collaborate with the HoloLens. |
+| Mobile device (optional)   | Android or iOS                    | You can use a mobile device to collaborate with the HoloLens. Inking, annotations, and image insertion are not currently available on mobile.                        |
+
+> [!Note]
+> RS1 OS build 10.0.14393.0 is the minimum HoloLens build that supports Remote Assist. We recommend updating the HoloLens to newer versions when they are available.
+
+### Licensing & product requirements
+
+| Product required                  | Details           | Learn more        |
+|:----------------------------------|:------------------|:------------------|
+| Azure Active Directory (Azure AD) | Required to log users into the Remote Assist app through Microsoft Teams. Also required for app distribution through the [Microsoft Store for Business](https://docs.microsoft.com/en-us/microsoft-store/sign-up-microsoft-store-for-business). If you choose not to distribute the app through the Microsoft Store for Business, users can also install Remote Assist on a HoloLens or PC from the [Microsoft store](https://www.microsoft.com/en-us/store/apps) using their Microsoft Account credentials (MSA). | [Get started with Azure AD](https://docs.microsoft.com/en-us/azure/active-directory/get-started-azure-ad) |
+| Microsoft Teams                   | Microsoft Teams is the backbone that facilitates communication in Remote Assist. All devices that will make calls to the HoloLens will need to have Microsoft Teams installed. | [Overview of Microsoft Teams](https://docs.microsoft.com/en-us/MicrosoftTeams/teams-overview) |
+| Microsoft Office 365              | Because Microsoft Teams is part of Office 365, all users who will make calls from their PC/phone to the HoloLens will need an Office 365 license. | [Office 365 licensing for Microsoft Teams](https://docs.microsoft.com/en-us/MicrosoftTeams/office-365-licensing) |
+
+### Network requirements
+
+1.5 MB/s is the recommended bandwidth for optimal performance of Microsoft Remote Assist. Though audio/video calls may be possible in environments with reduced bandwidth, you may experience HoloLens feature degradation, limiting the user experience. To test your company’s network bandwidth, we suggest following the steps outlined below:
+
+   1. Have a mobile Teams user (iOS or Android) video call a desktop Teams user.
+   2. Once the video call has been successfully connected between user 1 and 2, add another separate video call between a 3rd and 4th user, and another for a 5th and 6th user.
+   3. Continue adding video callers to stress test your network bandwidth until confident that multiple users can successfully connect on video calls at the same time.
+
+See [Preparing your organization's network for Microsoft Teams](https://docs.microsoft.com/en-us/MicrosoftTeams/prepare-network) to learn more.
+
+## Microsoft Layout
+
+Bring designs from concept to completion with confidence and speed using Microsoft Layout. Import 3D models to easily create room layouts in real-world scale. Experience designs as high-quality holograms in physical or virtual space and edit in real time. With Microsoft Layout, see ideas in context, saving valuable time and money.
+
+Below, you'll find the device options, and technical requirements, you'll need to consider in order to distribute Layout throughout your organization when it's available from the [Microsoft Store](https://www.microsoft.com/en-us/store/apps) and [Microsoft Store for Business](https://businessstore.microsoft.com/en-us/store) on May 22, 2018.
+
+### Device options
+
+You can use Microsoft Layout with a HoloLens, or with a Windows Mixed Reality immersive headset with motion controllers.
+
+#### HoloLens requirements
+
+| OS requirements                   | Details                                                    |
+|:----------------------------------|:-----------------------------------------------------------|
+| HoloLens, with RS4 build          | This build will be available as a HoloLens update on May 22, to align with the app release. Instructions for upgrading to the RS4 OS build are forthcoming. |
