+## Usage
+
+* Close all VR applications, SteamVR and Oculus desktop software if running
+* Launch the tool. It will require Administrator rights for restarting OVRService
+* Select Touch controller to calibrate in dropdown menu
+* To increase deadzone, decrease values -X and -Y or increase values of +X and +Y. I recommend increasing and decreasing values by about 50
+* Press Save button then Restart OVRService
+* Launch Oculus software and check if issue is fixed
+* Repeat above steps if you still experiencing thumbstick self-activation issue. In some extreme cases you may need to change deadzone value by about 200. For example when my thumbstick started behaiving weird I had to decrease -X deadzone from 502 to 380.
