 ## Development Note
 
-### FAQ: Why are my particle effects not displayed correctly?
-
-If `ParticleSystem` alone displays particles correctly but `UIParticle` does not, please check the following points:
-
-* [Shader Limitation](https://github.com/mob-sakai/ParticleEffectForUGUI#shader-limitation)
-  * Most cases can be solved by using `UI/Additive` or `UI/Default`.
-* Particles are masked
-  * `UIParticle` is maskable.
-  * Set `Mask` or `RectMask2D` component properly.
-* Particles are too small
-  * If particles are small enough, they will not appear on the screen.
-  * Increase the `Scale` value.
-  * If you don't want to change the apparent size depending on the resolution, try `Auto Scaling` option.
-* Particles are too many
-  * No more than 65535 vertices can be displayed (for mesh combination limitations).
-  * Please set `Emission` module and `Max Particles` of ParticleSystem properly.
-* Particles are emitted off-screen.
-  * When `Position Mode = Relative`, particles are emitted from scaled position of the ParticleSystem, not from the screen point of the ParticleSystem.
-  * Place the ParticleSystem in the proper position or try `Position Mode = Absolute`.
-* Attaching `UIParticle` to the same object as `ParticleSystem`
-  * `Transform.localScale` will be overridden by `Auto Scaling` option.
-  * It is recommended to place `ParticleSystem` under `UIParticle`.

 ### Shader Limitation
 
-The use of UI shaders is recommended.
+UIParticles are based on UIVertex.  
-
+Therefore, only xy components is available for each UV in the shader. (zw components will be ignored).  
-- If you need a simple Additive shader, use the `UI/Additive` shader instead.
-- If you need a simple alpha-blend shader, use the `UI/Default` shader instead.
-- If your custom shader does not work properly with UIParticle, consider creating a custom UI shader.
-
-#### Built-in shaders are not supported
-
-UIParticle does not support all built-in shaders except for `UI/Default`.  
-If their use is detected, an error is displayed in the inspector.  
-Use UI shaders instead.
-
-#### UV.zw components will be discarded
-
-UIParticleRenderer renders the particles based on UIVertex.  
-Therefore, only xy components is available for each UV in the shader. (zw components will be discarded).  
 So unfortunately UIParticles will not work well with some shaders.  
-
-#### Custom vertex streams
-
 When using custom vertex streams, you can fill zw components with "unnecessary" data.

+- If you need a simple Additive shader, use the `UI/Additive` shader instead.

+- If you need a simple alpha-blend shader, use the `UI/Default` shader instead.
