-### Breaking Changes
-
- The default value of `UIParticle.scale` has been changed from `10` to `1`.
- `UIParticle` no longer inherits from `MaskableGraphic`.
- 
+1. Download a source code zip file from [Releases](https://github.com/mob-sakai/ParticleEffectForUGUI.git/releases) and extract it.
+2. Place it in your project's `Packages` directory.

 `UIParticle` controls the ParticleSystems that are attached to its own game objects and child game objects.

+  use this to mark as animatable.
 - **Mesh Sharing**: Particle simulation results are shared within the same group. A large number of the same effects can
  be displayed with a small load. When the `Random` toggle is enabled, it will be grouped randomly.
+  - **None:** Disable mesh sharing.
+  - **Auto:** Automatically select Primary/Replica.
+  - **Primary:** Provides particle simulation results to the same group.
+  - **Primary Simulator:** Primary, but do not render the particle (simulation only).
+  - **Replica:** Render simulation results provided by the primary.
 - **Position Mode**: Emission position mode.
-    - **Absolute:** Emit from the world position of the `ParticleSystem`.
-    - **Relative:** Emit from the scaled position of the `ParticleSystem`.
- **Auto Scaling**: `Transform.lossyScale` (=world scale) will be set to `(1, 1, 1)` on update. It prevents the
-  root-Canvas scale from affecting the hierarchy-scaled `ParticleSystem`.
+  - **Absolute:** The particles will be emitted from the world position.
+  - **Relative:** The particles will be emitted from the scaled position.
+- **Auto Scaling Mode**: How to automatically adjust when the Canvas scale is changed by the screen size or reference resolution.
+  - **None:** Do nothing.
+  - **Transform:** Transform.lossyScale (=world scale) will be set to (1, 1, 1).
+  - **UIParticle:** UIParticle.scale will be adjusted.
+- **Use Custom View:** Use this if the particles are not displayed correctly due to min/max particle size.
+  - **Custom view size:** Change the bake view size.
 - **Rendering Order**: The ParticleSystem list to be rendered. You can change the order and the materials.

 **NOTE:** Press the `Refresh` button to reconstruct the rendering order based on children ParticleSystem's sorting order
