 ![Build my project 😎](https://github.com/chenjd/Render-Crowd-Of-Animated-Characters/workflows/Build%20my%20project%20%F0%9F%98%8E/badge.svg)
 
 #### Description：
-Updated to Unity 2019 or later.
+Using GPU to implement large-amount animation characters rendering. The animation map for vertex shader to modify the vertex position of the mesh at runtime. Useing GPU instancing to reduce draw calls.
 
-Using GPU to achieve large number of animated characters rendering.
+The initial version was released on GitHub on 30 Jul 2017, and of course, it is still on GitHub. However, if you can buy me **a cup of coffee**, I will be very
+happy :-).

-* anim map for vertex shader to modify the vertex position of the mesh at runtime.
 
-* use gpu instancing to reduce draw call.
+Recently I added support for Unity 2019, so it can be used from Unity 5.x to Unity 2019.
+
+And I will create a video tutorial to demonstrate how to use it. If you want to know more about the implementation behind it, you can read this [article](https://medium.com/chenjd-xyz/how-to-render-10-000-animated-characters-with-20-draw-calls-in-unity-e30a3036349a) I wrote.
+
+#### Features:
+✓Using the animation map to modify the position of vertices of your characters at runtime to avoid a lot of cost of skin calculation.
+✓Using GPU Instancing to reduce the number of draw calls, only 20 draw calls are
+needed to render 10,000 soldiers playing attack actions in the demo scene.
+
