1. In Player Settings..., find the Other Settings group and click on the header bar.
2. Check the Virtual Reality Supported checkbox.
3. You should see Windows Holographic in the list of Virtual Reality SDKs (or, Windows Mixed Reality, depending on your version of Unity).

4. If not, click on + to add it:

Projects that use MixedRealityToolkit can skip to the Building and running section. Projects that are using Vuforia with HoloLens, such as the one we begin in the next chapter, will also need to configure Vuforia.
