+        Here is an example of using the :class:`LSM6DS3TRC` class.
         First you will need to import the libraries to use the sensor
 
         .. code-block:: python
 
             import board
-            from adafruit_lsm6ds.lsm6ds3 import LSM6DS3
+            from adafruit_lsm6ds.lsm6ds3trc import LSM6DS3TRC
 
         Once this is done you can define your `board.I2C` object and define your sensor object
 
         .. code-block:: python
 
             i2c = board.I2C()  # uses board.SCL and board.SDA
-            sensor = LSM6DS3(i2c)
+            sensor = LSM6DS3TRC(i2c)
 
         Now you have access to the :attr:`acceleration` and :attr:`gyro`: attributes
