 ## Get started with the Mixed Reality Toolkit (MRTK)
 
-The Mixed Reality Toolkit (MRTK) is a cross-platform toolkit for building mixed reality experiences. We'll use MRTK 2.5.1 for its interaction and visualization features.
-
-To add MRTK, follow the [Required steps](https://microsoft.github.io/MixedRealityToolkit-Unity/version/releases/2.5.1/Documentation/Installation.html#required) listed in the [MRTK Installation Guide](https://microsoft.github.io/MixedRealityToolkit-Unity/version/releases/2.5.1/Documentation/Installation.html).
-
-Those steps are:
- - [Get the latest MRTK Unity packages](https://microsoft.github.io/MixedRealityToolkit-Unity/version/releases/2.5.1/Documentation/Installation.html#1-get-the-latest-mrtk-unity-packages)
-     - Even though it says "latest", please use version 2.5.1 from the MRTK release page.
-     - We only use the *Foundation* package in this tutorial. The *Extensions*, *Tools*, and *Examples* packages are not required.
- - [Import MRTK packages into your Unity project](https://microsoft.github.io/MixedRealityToolkit-Unity/version/releases/2.5.1/Documentation/Installation.html#2-import-mrtk-packages-into-your-unity-project)
- - [Switch your Unity project to the target platform](https://microsoft.github.io/MixedRealityToolkit-Unity/version/releases/2.5.1/Documentation/Installation.html#3-switch-your-unity-project-to-the-target-platform)
-     - You should have done this step already in the first chapter, but now is a good time to double check!
- - [Add MRTK to a new scene or new project](https://microsoft.github.io/MixedRealityToolkit-Unity/version/releases/2.5.1/Documentation/Installation.html#4-add-and-configure-mrtk-with-a-new-scene)
-     - You can add MRTK to a new scene and re-add your coordinator and model objects/scripts, or you can add MRTK to your existing scene using the *Mixed Reality Toolkit -> Add to Scene and Configure* menu command.
+The Mixed Reality Toolkit (MRTK) is a cross-platform toolkit for building mixed reality experiences. We'll use MRTK 2.8.3 for its interaction and visualization features.
+
+The [official guide](https://learn.microsoft.com/training/modules/learn-mrtk-tutorials/1-5-exercise-configure-resources?tabs=openxr) to import MRTK contains some steps we don't need to do. Only these are necessary:
+ - Importing the 'Mixed Reality Toolkit/Mixed Reality Toolkit Foundation' version 2.8.3 to you project through the Mixed Reality Feature Tool ([see](https://learn.microsoft.com/training/modules/learn-mrtk-tutorials/1-5-exercise-configure-resources?tabs=openxr#import-the-mrtk-unity-foundation-package)).
+ - Run the configuration wizard of MRTK ([see](https://learn.microsoft.com/training/modules/learn-mrtk-tutorials/1-5-exercise-configure-resources?tabs=openxr#configure-the-unity-project)).
+ - Add MRTK to the current scene ([see](https://learn.microsoft.com/training/modules/learn-mrtk-tutorials/1-5-exercise-configure-resources?tabs=openxr#create-the-scene-and-configure-mrtk)). There is no need to change the MRTK profile here, as we will switch to the ARR profile very soon.

-The **AppMenu** has a sub menu **Model Tools** that implements a view controller for binding with the model. When the GameObject contains a **RemoteBounds** component, the view controller will add a [**BoundingBox**](https://microsoft.github.io/MixedRealityToolkit-Unity/Documentation/README_BoundingBox.html) component, which is an MRTK component that renders a bounding box around an object with a **BoxCollider**. A [**ObjectManipulator**](https://microsoft.github.io/MixedRealityToolkit-Unity/version/releases/2.5.1/api/Microsoft.MixedReality.Toolkit.UI.ObjectManipulator.html), which is responsible for hand interactions. These scripts combined will allow us to move, rotate, and scale the remotely rendered model.
