 ## Features
 ### Collisions
 
-4 types of collisions are available: ground, sphere, capsule, and infinite plane. Colliders can be created with [maya_expressionCollision](https://github.com/akasaki1211/maya_expressionCollision).  
-
-![collisions](.images/collisions.gif)
+5 types of collisions are available: **Sphere, Capsule, Infinite plane, Mesh, and Ground**.  
 
 - `Radius` : Radius of the end-joint.  
-- `Iterations` : Higher values increase the accuracy of collisions. Recommended value is 3 to 5. 0 disables collisionss.  
-- `Enable Ground Col` : Enable ground collision.  
-- `Ground Height` : Height of the ground.  
-- `Sphere Col Matrix` : Connect the sphere collider worldMatrix.  
-- `Sphere Col Radius` : Radius of sphere collider.  
-- `Capsule Col Matrix A` `Capsule Col Matrix B` : Connect worldMatrix on one side of the capsule collider.  
-- `Capsule Col Radius A` `Capsule Col Radius B` : Connect the radius of one side of the capsule collider.  
-- `Infinite Plane Col Matrix` : Connect worldMatrix of infinite plane collider.  
+- `Iterations` : Higher values increase the accuracy of collisions. Recommended value is 3 to 5. 0 disables collisions.  
 
-The attributes that connect the collider are in a list, so you can use more than one. Ground Collision do not need connections.  
+Collisions are determined by the sphere centered around the end-joint. The radius of the end-joint is set with the Radius attribute.

+
+The required connections for these three types of collisions are as follows.  
+
+- `Sphere Col Matrix` : Connect the sphere collider worldMatrix.  
+- `Sphere Col Radius` : Radius of sphere collider.  
+- `Capsule Col Matrix A` `Capsule Col Matrix B` : Connect worldMatrix on one side of the capsule collider.  
+- `Capsule Col Radius A` `Capsule Col Radius B` : Connect the radius of one side of the capsule collider.  
+- `Infinite Plane Col Matrix` : Connect worldMatrix of infinite plane collider.

 > 💡**Note**  
-> Colliders do not necessarily need to use [expcol](https://github.com/akasaki1211/maya_expressionCollision). It can be anything as long as the required attributes are connected.  
+> Colliders can be created with [maya_expressionCollision (expcol)](https://github.com/akasaki1211/maya_expressionCollision), but it is not necessary to use it. Any collider can be used as long as the required attributes are connected.

+#### Mesh (*Experimental)
+
+![mesh_collision](.images/mesh_collision.gif)
+
+Any mesh can be used for collisions. Compared to other types of collisions, mesh collisions are more loaded and less stable, so their use is not recommended.  
+
+- `Mesh Collider` : Connect worldMesh of any mesh.  
+- `Mesh Col Cutoff` : Max distance for mesh collision detection.  
+
+> 💡**Note**  
+> - As this is an **experimental** feature, it may be unstable.  
+> - All edges of the collision mesh should be made with **soft edges**.  
+> - If the collision mesh has a large number of polygons, it will increase the processing load.  
+> - If the collision mesh is not a closed shape, use `Mesh Col Cutoff` to control the range of detections.

+#### Ground
+
+![ground_collision](.images/ground_collision.png)
+
+A horizontal infinite plane collision. It can be used only with the enable and ground height attribute, no connections are needed.  
+
+- `Enable Ground Col` : Enable ground collision.  
+- `Ground Height` : Height of the ground.

 ### Angle Limitation
 
 The `Angle Limit` attribute allows for limiting the rotation angle of bones. It has a higher priority than collision, so depending on the posture, it may be penetrated in the colliders.
