+## Servo on Hololens.
+
+How to compile and run:
+
+With Visual Studio **2019**:
+- Open `support/hololens/ServoApp.sln`
+- click on *restore nugets packages* under the context menu of "Solution" (in the right panel). This will automatically download Angle which comes with libEGL.dll, necessary to build servo.
+
+In your Visual Studio **2017** cmd prompt:
+- make sure libEGL.dll is in your `%LIB%` path: `set LIB=%LIB%;c:\XXX\servo\support\hololens\packages\ANGLE.WindowsStore.2.1.13\bin\UAP\x64\`
+- compile servo: `mach build -d --uwp`
+
+With Visual Studio **2019**:
+- Select emulator or local machine, select configuration (Debug or Release) and press run
+- VS will look for the DLLs and .h in `../../target/debug|release/` (depending on the configuration you selected in VS) and copy them in the final package.
+
+For now, it's not possible to interact with the web page.
+
+Note: to build the project with MSBuild:
+- `MSBuild ServoApp.sln /p:Configuration=Debug /p:Platform=x64`
