 **LC** originates from the initials of the author's name. The library was initially designed to help the author develop small projects and gain development experience. However, the author did not gain a competitive advantage in the job market, which is crowded with C/C++ experts, and thus had to work in web front-end development. As a result, LCUI now leans towards integrating technologies from the web front-end domain.
 
-### Main Features
+### Key Features  
 
-- **Cross-Platform:** Supports Windows and Linux.
-- **Fully Custom-Drawn Components:** Components maintain a consistent appearance and behavior across multiple platforms.
-- **Built-in CSS Engine:** Supports using CSS to define the style and layout of the user interface, making it easier to get started for those with web development experience.
-- **Provides Modern Development Tools:** The tools allow you to use the [TypeScript](https://lcui-dev.github.io/docs/guide/typescript) language with JSX syntax, the React library, and other web front-end technologies to write user interfaces.

-  - Improve API design.
-  - Enhance the CSS engine to support `inherit`, `!important`, and escape characters.
-  - Add [SDL](https://www.libsdl.org/) backend to replace the lib/ptk library.
-  - Adapt to other open-source graphics libraries for better rendering performance.
-- Command-line Tools
-  - `lcui build --watch`: Continuously monitor file changes and automatically rebuild.
-  - `lcui dev-server`: Similar to webpack-dev-server, builds the LCUI application as a website for developers to preview interfaces in the browser.
-  - Add build cache to rebuild only files that have changed.
-- React Component Library: Referencing some web frontend component libraries (e.g., [radix](https://www.radix-ui.com/), [shadcn/ui](https://ui.shadcn.com/)), develop a TypeScript + React component library suitable for LCUI applications, reusing components from the [LC Design](https://github.com/lcui-dev/lc-design) component library.

+**Why should I choose LCUI over other GUI libraries/frameworks?**  
 
-No, you can think of it as a traditional GUI development library that applied some Web technologies.
+It's recommended to prioritize other GUI libraries/frameworks, as LCUI currently lacks:  
 
-**Since it supports the use of TypeScript language, why don't I use Electron?**
+- **A rich set of built-in components:** You will need to build almost all the components in your interface from scratch, leading to higher development costs.  
+- **Efficient graphics rendering performance:** Interfaces with extensive and complex content may experience lag.  
+- **An animation system:** The lack of visual feedback affects the user interaction experience.  
 
-Yes, if you have web development experience and are willing to learn Electron, then Electron is obviously the best choice.
+Given its current state, LCUI is best suited for fulfilling the author's personal needs or developing simple tools with minimal interface content and interactions.  
 
-Given LCUI's current capabilities, it is primarily suitable for meeting the author's personal needs and developing simple tools.
+**Support development with TypeScript? If I know how to use it, why wouldn’t I just go with Electron?**
 
-**Why should I choose LCUI over other GUI libraries/frameworks?**
+Currently, TypeScript is primarily used to describe UI and resource dependencies, with only a few TypeScript features in use. You don’t need to study it in depth; in most cases, you can simply refer to example code for implementation.
 
-We suggest that you prioritize other GUI libraries/frameworks.
+If you have extensive web development experience and are willing to learn Electron, then Electron is clearly the better choice.
