 A composed rotation + mirror is obtained by applying the corresponding
 rotation to the solved cube mirrored along the M plane.
 
+For example, to apply the transformation RBm (mirrored RB) to a cube C:
+        1a. Apply a mirror along the M plane to the solved cube
+        1b. Rotate the mirrored cube with z' y2
+        3.  Apply the cube C to the transformed solved cube
+        4.  Apply the transformations of step 1a and 1b in reverse
+
 The orientation of pieces after a rotation ignores the new position
 of centers.  A rotated cube can technically be inconsistent, because
 the parity of the edge permutation has to be adjusted considering the
