+**Tag: `seg_`**<br>
+ 
+Segment bone is a special type of bone that is animated procedurally, following the parent bone using the least amount of
+movement required through rotation or position. This is very useful when creating dynamic models such as worms, tails and 
+hair.
+
+As of R4.0.7, segment tag can only be used on cube-less bones. The pivot point of the bone should also be placed at the 
+back. The bones can be further configured by using the [Segment](/MythicMobs/mechanics/model/Segment) mechanic.
+
+Check out this [segment demo](../Assets/Demo/segment_demo.zip) as reference for how to set up the bones and use the segment
+mechanic.
