+HelloSensorCore is a quick start sample demonstrating the usage of Step Counter API. The sample shows how to initialise and use StepCounter API. 
+
+1. Instructions
+--------------------------------------------------------------------------------
+
+Learn about the Lumia SensorCore SDK from the Lumia Developer's Library. The
+example requires the Lumia SensorCore SDK's NuGet package but will retrieve it
+automatically (if missing) on first build.
+
+To build the application you need to have Windows 8.1 and Windows Phone SDK 8.1
+installed.
+
+Using the Windows Phone 8.1 SDK:
+
+1. Open the SLN file: File > Open Project, select the file `HelloSensorCore.sln`
+2. Remove the "AnyCPU" configuration (not supported by the Lumia SensorCore SDK)
+or simply select ARM
+3. Select the target 'Device'.
+4. Press F5 to build the project and run it on the device.
+
+Alternatively you can also build the example for the emulator (x86) in which case
+the Steps will use simulated data.
+
+Please see the official documentation for
+deploying and testing applications on Windows Phone devices:
