-A simple GitHub template that lets you create a [Taipy GUI](https://github.com/Avaiga/taipy-gui)
-extension library that contains visual elements with dynamic properties therefore coded
-with React.
+A GitHub template to create a [Taipy GUI](https://github.com/Avaiga/taipy-gui) extension library, using React for dynamic visual components.
 
-You can find the Taipy GUI Extension Libraries documentation in
-[this section](https://docs.taipy.io/en/latest/manuals/gui/extension/)
-of the Taipy GUI User Manual.
+See the [official documentation](https://docs.taipy.io/en/latest/manuals/gui/extension/) for more information on Taipy GUI extension libraries.
 
-This template contains all the code that lets you build a Taipy GUI Extension Library
-containing a single element and use this library in a tiny Taipy GUI application.<br/>
-This code is meant to be modified so you can add your custom visual elements.
