 ### Normalized Human Bones
 
 From VRM1.0, VRM models can have “non-normalized” orientations for each human bone.
-
 Due to this change, we introduce a feature to access “normalized” human bones to maintain compatibility between models with different bone orientations.
-
 Normalized human bones have identity orientation (`[0, 0, 0; 1]` in quaternion) in its rest pose.
 
 Almost all members of `VRMHumanoid` existed in v0.x were deprecated.
-
 We now have members to access raw (original) human bones and normalized human bones instead.
-
 For example, you can get a `THREE.Object3D` of a human bone by either `VRMHumanoid.getRawBoneNode` or `VRMHumanoid.getNormalizedBoneNode`.
 
 Normalized human bones are proxy objects of raw human bones.
-
 Operations applied to normalized human bones are automatically synced to raw human bones upon `VRM.update` or `VRMHumanoid.update`.
-
 If you don’t need this behavior, set `VRMHumanoid.autoUpdateHumanBones` to `false`.
