+Background sensors sample
+===========================
+
+This sample shows how to use background tasks with a device use trigger targetting sensors APIs. For the sake of the example, the [**Accelerometer**](http://msdn.microsoft.com/library/windows/apps/br225687) API is used in this sample.
+
+**Note** The Universal Windows app samples require Visual Studio 2015 to build and Windows 10 to execute.
+
+This sample allows the user to view the event count. Only one scenario is available:
+
+-   Device use trigger
+
+**Device use trigger**
+
+When you choose the **Enable** button for the **Device use trigger** option, the app registers a background task that listens for accelerometer readings and count them.
+
+**Note**  For Windows 8 app samples, download the [Windows 8 app samples pack](http://go.microsoft.com/fwlink/p/?LinkId=301698). The samples in the Windows 8 app samples pack will build and run only on Microsoft Visual Studio 2012.

+
+Build the sample
+----------------
+
+1.  Start Visual Studio 2015 and select **File** \> **Open** \> **Project/Solution**.
+2.  Go to the directory to which you unzipped the sample. Then go to the subdirectory containing the sample in the language you desire - either C++ or C\#. Double-click the Visual Studio 2015 Solution (.sln) file.
+3.  Press Ctrl+Shift+B, or select **Build** \> **Build Solution**.
+
+Run the sample
+--------------
+
+The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
+
+**Deploying the sample**
+
+1.  Select **Build** \> **Deploy Solution**.
+
+**Deploying and running the sample**
+
+1.  To debug the sample and then run it, press F5 or select **Debug** \> **Start Debugging**. To run the sample without debugging, press Ctrl+F5 or select**Debug** \> **Start Without Debugging**.
