 # Printer Skew Correction.  It is possible to use software to correct
 # printer skew across 3 planes, xy, xz, yz.  This is done by printing
-# a calibration model along a plane and measuring three lengths.  See
-# skew_correction.md in the docs directory for more details.

+# to the nature of skew correction these lengths are set via gcode. See

-#xy_ac_length:
-#xy_bd_length:
-#xy_ad_length:
-#   The measured lengths (in mm) on the xy plane skew calibration print.
-#   If one length is provided all three lengths must be provided.  The default
-#   is no measurement, which results in no skew correction along the xy plane.
-#xz_ac_length:
-#xz_bd_length:
-#xz_ad_length:
-#   The same as above, on the xz plane.  The default is no skew correction
-#   on the xz plane.
-#yz_ac_length:
-#yz_bd_length:
-#yz_ad_length:
-#   The same as above on the yz plane.  The default is no skew correction
-#   on the yz plane.
