-	After calibrating the module and securing it to your vehicle such that it's
-  stable within 2 degrees, and the board is oriented correctly with regards to
-  the vehicle's frame, you can now read the vehicle's "attitude". The attitude
-  includes the vehicle's heading, pitch, and roll. You can also check the
-  accuracy of those readings. 
+  getEsfAlignment (UBX-ESF-ALG) reports the status and alignment angles of the IMU within the vehicle.
+  These define the rotation of the IMU frame within the vehicle (installation frame) - not the heading
+  of the vehicle itself. The vehicle attitude solution is reported separately by getNAVATT (UBX-NAV-ATT).
