  1. Extract steamvr.driver.zip and copy imuFBT folder to (Steam directory)\steamapps\common\SteamVR\drivers.  
  2. Extract esp32.sketch.zip, edit the settings (pin settings, etc.) in esp32_settings.h file.  
  3. Upload the sketch to ESP32 microcontroller with Arduino IDE (SparkFun_BNO080_Arduino_Library Arduino library is required).  
- 4. Extract desktop.server.zip and run imufbtserver.exe (might trigger antivirus false positive, known problem for unsigned PyInstaller exe files).  
- 5. Set the tracker sensor frame to driver frame (X right, Y up, Z back) XYZ intrinsic rotation based on the mounting orientation, body segment length, tracker position and offset settings when standing in T-pose** in **Main settings** and **Offset settings** tab.  
- 6. Activate required tracker devices to be output to SteamVR. In some SteamVR game/program, the hand controllers might lose tracking or not working if too many tracker devices are activated.  
- 7. Set the tracker floor level offset (tracker min Y value) if necessary.  
- 8. Enable override feet tracker data with lower leg tracker data if want to use lower leg tracker as foot role. Feet tracker device must still be activated.  
- 9. Save the settings by pressing **Save settings** button or load an existing saved settings by pressing **Load settings** button in **Main settings** tab. The last saved/loaded settings will be automatically loaded in the next instance.  
+ 4. Extract desktop.server.zip. Add imufbtserver.exe and backend/imuFBTServerBackend.exe to Windows firewall exception list to allow UDP to work properly.

+ 7. Activate required tracker devices to be output to SteamVR. In some SteamVR game/program, the hand controllers might lose tracking or not working if too many tracker devices are activated.  
+ 8. Set the tracker floor level offset (tracker min Y value to prevent clipping) if necessary.  
+ 9. Enable lower leg tracker data as SteamVR feet tracker if want to use lower leg tracker as foot role. Feet tracker device must still be activated.  
+ 10. Save the settings by pressing **Save settings** button or load an existing saved settings by pressing **Load settings** button in **Main settings** tab. The last saved/loaded settings will be automatically loaded in the next instance.
