-## 为什么使用 Dioxus 和 Rust ？
-
-TypeScript 是一个不错的 JavaScript 拓展集，但它仍然算是 JavaScript。
-
-TS 代码运行效率不高，而且有大量的配置项。

-相比之下，Dioxus 使用 Rust 编写将大大的提高效能。
+## Why Dioxus?
 
-使用 Rust 开发，我们能获得：
+目前有非常多的应用开发选择，为什么偏偏要选择 Dioxus 呢？
 
-- 静态类型支持。
-- 变量默认不变性。
-- 简单直观的模块系统。
-- 内部集成的文档系统。
-- 先进的模式匹配系统。
-- 简洁、高效、强大的迭代器。
-- 内置的 单元测试 / 集成测试。
-- 优秀的异常处理系统。
-- 强大且健全的标准库。
-- 灵活的 `宏` 系统。
-- 使用 `crates.io` 管理包。
+首先，Dioxus将开发者的经验放在首位。这反映在 Dioxus 特有的各种功能上。
 
-Dioxus 能为开发者提供的：
+- 自动格式化 RSX 格式代码，并拥有 VSCode 插件作为支持。
+- 热加载基于 RSX 代码解析器，同时支持桌面程序和网页程序。
+- 强调文档的重要性，我们对所有 HTML 元素都提供文档支持。
 
-- 安全使用数据结构。
-- 安全的错误处理结果。
-- 拥有原生移动端的性能。
-- 直接访问系统的IO层。
+Dioxus 也是一个可扩展化的平台。
 
-Dioxus 使 Rust 应用程序的编写速度和 React 应用程序一样快，但提供了更多的健壮性，让团队能在更短的时间内做出强大功能。
+- 通过实现一个非常简单的优化堆栈机，轻松构建新的渲染器。
+- 构建并分享开发者自定义的组件代码。
 
-### 不建议使用 Dioxus 的情况？
+Dioxus 那么优秀，但什么时候它不适合我呢？
+- 它还没有完全成熟。api仍在变化，可能会出现故障（尽管我们试图避免）
+- 您需要运行在 no-std 的环境之中。
+- 你不喜欢使用 React-like 的方式构建 UI 项目。
 
-您不该在这些情况下使用 Dioxus ：
 
-- 您不喜欢类似 React 的开发风格。
-- 您需要一个 `no-std` 的渲染器。
-- 您希望应用运行在 `不支持 Wasm 或 asm.js` 的浏览器。
-- 您需要一个 `Send + Sync` UI 解决方案（目前不支持）。
+## 贡献代码
