-## About this project
+## **About This Project**
 
-RszTool is a tool that edit and create resource file for RE ENGINE game. Currently support .user, .pfb and .scn files.  
-RszTool is inspired by [RE_RSZ](https://github.com/alphazolam/RE_RSZ) and [EMV-Engine/RE Engine Resource Editor](https://github.com/alphazolam/EMV-Engine) by alphazolam.  
-RszTool also provide some advanced operations like copy/paste/remove/duplicate for instance array/game object.  
-RszTool is developed with C# and WPF. You can also use RszTool.dll as a C# library to do some batch work.  
+RszToolEx is a refined and enhanced utility for editing and creating resource files for RE ENGINE games, with a particular focus on facilitating modding for Resident Evil titles. This tool builds upon the foundation laid by the original [RszTool](https://github.com/czastack/RszTool) by czastack, introducing significant improvements in performance, functionality, and user experience.
 
-## Why I make this tool
+Designed with modders in mind, RszToolEx simplifies the complex workflows associated with resource file manipulation, making it an essential tool for the RE ENGINE modding community.
 
-- RE_RSZ is a good tool. But it is 010 Editor Binary Template, so it need refresh action when struct changed. And sometimes it take several minutes to open a complex file. Also it lacked some advanced operations like copy/paste for hierarchical instance/game object. You need manual create many instances and set object index to another instance.
-- EMV-Engine/RE Engine Resource Editor is a reframework lua script. You need to open the game first to use it. It provide limited file access. For example, it is not convenient to open file or drop file into it. It provide some function like adding item inspire me.
+---
 
-I want a faster and rich functional tool to edit resource file. So I make this tool.

-## How to use this tool
-
-- Download the latest release [here](https://github.com/czastack/RszTool/releases).
-- You need to copy rszxxx.json to the same folder of RszTool.App.exe from RE_RSZ manually.
-- Currently, RszTool.App support Chinese and English, it will choose language according to your system culture.
-- RszPatchs/rszxxx_patch.json will replace some data in rszxxx.json. Because sometimes auto detected type for "Data" type is not correct.
-- You can Click File/Open menu or drag and drop file to RszTool.App window to open it.
-- Right click for array item/game object to see some operation context menu. I think it is good to use.

-- You can search instances and game objects in bottom of the page.
