 # Godot-Shader-Lib
-Visual shader node library for Godot engine. The addon supports Godot versions 4.x!
+Visual shader node library for Godot engine. Supports all 4.2.0+ versions!
 
 Adds various extra nodes to use in built-in visual shader editor.
-# Installation
-Copy the contents of **_addons/ShaderLib_** into the same folder in your project. No activation needed. Custom visual shader nodes work the same way as standard visual shader nodes.
 
-If you don't immediatly see new nodes under **_Addons_** category, simply reload your project.
-# Uninstallation
-Delete the contents of **_addons/ShaderLib_** folder from your project. Make sure to delete it using the Godot editor instead of your default file system program.

+# Installation
+Hit download as zip button in the git repo. Copy the contents of **_addons/ShaderLib_** into the same folder in your project. No activation needed. Custom visual shader nodes work the same way as standard visual shader nodes.
+
+If you don't immediatly see new nodes under **_Addons_** category, simply reload your project.
+# Uninstallation
+Delete the contents of **_addons/ShaderLib_** folder from your project. Make sure to delete it using the Godot editor instead of your default file system program.
+# Special Note
+Even if you don't use visual shader, you can still use this addon for writing your custom shaders.
+
+For example if you want to rotate UV in your **_.gdshader_** file, you can use `rotate_uv()` of this addon using `#include` keyword as following.
+`#include "res://addons/ShaderLib/UV/RotateUV.gdshaderinc"`
