What Unity Is
You can create any 2D and 3D game using Unity. You can make it with ease, you can make it highly-optimized and beautiful, and you can deploy it with a click to more platforms than you have fingers and toes. What’s more, you can use Unity’s integrated services to speed up your development process, optimize your game, connect with an audience, and achieve success.

System Requirements
Getting Started
This is the default layout of the Unity Project.
Unity build settings
We want to specify our Unity project to export as a Universal Windows Platform app.
Specify the export for Windows Holographic
In the Rendering section, check the Virtual Reality Supported checkbox to add a new Virtual Reality Devices list and confirm "Windows Holographic" is listed as a supported device.
Export the Visual Studio solution
Now your Unity project has all the settings applied to be properly exported as a Visual Studio solution for a HoloLens app.
Build and Deploy
All that's left is to build the Unity exported project, deploy it, and try it out on the device. Using the top toolbar in Visual Studio, change the target from Debug to Release and from ARM to X86. Now the instructions differ for deploying to a HoloLens versus the emulator. Follow the instructions that match your setup.
HoloLens over Wi-Fi
HoloLens over USB
