 ## Turning wheels calibration
 
+After each power-off, Rapha Rover loses the position of its turning wheels,
+requiring calibration. This process is initiated using the multifunctional
+button adjacent to the power button.
+
+To calibrate the wheels, press and hold the multifunctional button until the LED
+strips illuminate in blue. The turning wheels will begin rotating inwards to
+locate the induction sensor. Subsequently, the motors will continue rotating to
+calibrate their positions relative to the bumpers.
