+===============================================================================
+A CircuitPython module for calibrating the BNo055 9-DoF sensor. After manually
+calibrating the sensor, the module produces calibration offset tuples for use
+in project code.
+
+* Author(s): JG for Cedar Grove Maker Studios
+
+Implementation Notes
+--------------------
+**Hardware:**
+* Adafruit BNo055 9-DoF sensor
+**Software and Dependencies:**
+* Driver library for the sensor in the Adafruit CircuitPython Library Bundle
+* Adafruit CircuitPython firmware for the supported boards:
+  https://circuitpython.org/downloads
