 ## SDK Integration 
 
 The SDK is integrated in the example application by copying the sdk source and header files into the ```WEART_API_Integration/WEART_SDK``` directory, and adding them to the visual studio project.
+
+In addition, the application project includes the nuget package "Newtonsoft.Json" version 13.0.3, as it is a required dependency of the SDK.
+
 Most of the application code can be found in the ```WEART_API_Integration/MainPage.xaml.cs``` file.

+### Raw Sensors Data tracking
+
+In the right section of the window, the application displays the raw data of the different sensors aboard the TouchDIVER.
+In particular, it's possible to choose the hand and actuation point from which to visualize:
+* Timestamp of the last sample received
+* Accelerometer data (on the x,y,z axis)
+* Gyroscope data (on the x,y,z axis)
+* Time of Flight distance (in mm)
+
+To start receiving raw data, click on the "Start Raw Data" button, and to stop click on the "Stop Raw Data" button.
+
+When it's loaded, the application creates a WeArt.Components.WeArtRawSensorsDataTrackingObject for each pair of (HandSide, ActuationPoint).
+When one of the combo boxes values changes, the application adds a callback to the corresponding tracking object.
+The callback is responsible for displaying the received sample:

+The new SDK version is mostly compatible with the older versions.
 The only breaking change introduced relates to the WeArtTexture class, in which the ```VelocityX``` and ```VelocityY``` params has been removed because are not used anymore. The ```VelocityZ``` parameter has been renamed to ```Velocity```, and represents the speed at which the texture vibration is played by the thimble.
 
+## Dependencies
+The new SDK version has the following dependencies:
+* Newtonsoft.Json version >= 13.0.0 (currently tested with version 13.0.3)
+
+The dependencies can be found and installed by using the nuget package manager.
