-	  Say yes here to build support for the Bosch BMC150 accelerometer.
+	  Say yes here to build support for the following Bosch accelerometers:
+	  BMC150, BMI055, BMA250E, BMA222E, BMA255, BMA280.
+
 	  Currently this only supports the device via an i2c interface.
 
 	  This is a combo module with both accelerometer and magnetometer.
