+## Description
+
+
+
+This plugin uses new APIs `MeshBake/MashTrailBake` (added with Unity 2018.2) to render particles by CanvasRenderer.
+You can mask and sort particles for uGUI without Camera, RenderTexture, Canvas.
+
+Compares this "Baking mesh" approach with the conventional approach:
+(This scene is included in the package.)

+## Demo
+
+[WebGL Demo](http://mob-sakai.github.io/ParticleForUGUI)
+
+
+
+
+## Usage
+
+1. Download ParticleForUGUI.unitypackage from [Releases](https://github.com/mob-sakai/ParticleForUGUI/releases).
+1. Import the package into your Unity project. Select `Import Package > Custom Package` from the `Assets` menu.
+1. Add particle system to canvas.
+1. If you want to mask particles, set the "UI/UIAdditive" shader to material.
+1. Add `UIParticle` component to particle system from `Add Component` in inspector.
+
+1. Enjoy!
+
+
+##### Requirement
+
+* Unity 2018.2+ (Tested in Unity 2018.2b9)
+* No other SDK are required
+
+
+
+
+
+## Development Note
+
+#### BakeMesh API has a issue!
+
+See [this issue](https://issuetracker.unity3d.com/issues/bakemesh-slash-baketrailsmesh-crashes-if-update-jobs-are-running).
+
+`UIParticle` avoids the issue, but the rendering result lags one frame.
+
+Please vote the issue to improve `UIParticle`!
