    This option replaces the following setup with two additional bones:
 
-   #. An extra child bone of the target, rotated the same as its owner bone in rest pose.

    #. An extra sibling bone of the target, positioned same as the child in rest pose

       in *World Space* from the child.
-   #. The constraint uses *Local Space* of the sibling.
+   #. The constraint uses *Local Space* of the sibling instead of the original target.
 
    This video demonstrates the difference from ordinary *Local Space*:

       The setting reverses the weight values of the group.
 
+Sparse Bind
+   Only record bind data for vertices that have nonzero weights in the group at the time
+   of bind. This completely removes the memory and evaluation time overhead for the excluded
+   vertices, but adding new vertices to the group would require a rebind.
+
 Bind
    Bind the current state of the modified mesh to the current state of the target mesh,
    such that any later change in the target mesh will deform the modified mesh as well.
