 - 🔥 introduce an official plugin `enum-plus-plugin` that provides a collection of highly shareable plugins.
   - These plugins are designed to work in all scenarios and environments (including browser and Node.js), without introducing dependencies on third-party frameworks, component libraries, or platforms.
   - If you have a good idea that might be specific to a certain framework or platform rather than universally applicable, we recommend creating a new plugin project (e.g., `enum-plus-plugin-xxx`). We are happy to see that, and hope that you submit a PR to `enum-plus-plugin` to link your project back.

 ## Compatibility
 
-- **Browser Environments**:
+enum-plus is designed to be compatible with a wide range of environments, including modern browsers, Node.js, and various build tools. Below are the compatibility details for different environments:
 
-  - **Modern Bundlers**: With bundlers supporting the [exports](https://nodejs.org/api/packages.html#exports-sugar) field (Webpack 5+, Vite, Rollup), enum-plus targets `ES2020`. For broader browser support, transpile to earlier syntax using `@babel/preset-env` during your build process.
+### Browser Environments
 
-  - **Legacy Bundlers**: For tools without `exports` field support (like Webpack 4), enum-plus automatically falls back to the `main` field entry point, which targets `ES2016`.
+- **Modern Bundlers**: For bundlers supporting the [exports](https://nodejs.org/api/packages.html#exports-sugar) field (such as webpack 5+, vite, rollup), `es` directory is imported, which targets `ES2020`. For broader browser support, you can transpile to earlier syntax using `@babel/preset-env` during your build process.

+- **Legacy Bundlers**: For bundlers without [exports](https://nodejs.org/api/packages.html#exports-sugar) field support (like Webpack 4), this library automatically falls back to the `main` field entry point, and `es-legacy` directory is imported, which targets `ES2015`.
 
-    - `core-js`
-    - `@babel/preset-env` with appropriate `useBuiltIns` settings
-    - Alternative polyfill implementations
+- **UMD Version**: For direct browser usage or static projects without bundlers, enum-plus provides UMD version that can be included via a `<script>` tag. The `umd` directory contains two versions:
+  - `enum-plus.min.js`: Targets **`ES2020`**, suitable for modern browsers.
+  - `enum-plus-legacy.min.js`: Targets **`ES2015`**, suitable for older browsers.
 
-- **Node.js Compatibility**: enum-plus requires a minimum of `ES2016` features, compatible with Node.js `v7.x` and above.

 ## 兼容性
 
-enum-plus 提供了完善的兼容性支持。

-  - **现代打包工具**：对于支持 [exports](https://nodejs.org/api/packages.html#exports-sugar) 字段的打包工具（如 Webpack 5+、Vite、Rollup），enum-plus 的目标是 **`ES2020`**。如果需要更广泛的浏览器支持，可以在构建过程中使用 `@babel/preset-env` 转译为更早期的语法。
+- **现代打包工具**：对于支持 [exports](https://nodejs.org/api/packages.html#exports-sugar) 字段的打包工具（如 webpack 5+、vite、rollup），引入的是`es`目录，对应的 EcmaScript 版本是 **`ES2020`**。如果需要更广泛的浏览器支持，可以在构建过程中使用 `@babel/preset-env` 转译为更早期的语法。
 
-  - **旧版打包工具**：对于不支持 `exports` 字段的工具（如 Webpack 4），enum-plus 会自动回退到 `main` 字段的入口点，其目标是 **`ES2016`**。
+- **旧版打包工具**：对于不支持 [exports](https://nodejs.org/api/packages.html#exports-sugar) 字段的工具（如 webpack 4），enum-plus 会自动回退到 `main` 字段的入口点，引入的是`es-legacy`目录，对应的 EcmaScript 版本是 **`ES2015`**。
 
-  - **Polyfill 策略**：为了最小化包的体积，enum-plus 不包含任何 polyfill。如果需要支持旧版浏览器，可以引入以下内容：
+- **UMD版本**：为了方便在浏览器中直接使用，或者方便在没有打包工具的静态项目中使用，enum-plus 还提供了 UMD 版本，可以通过 `<script>` 标签引入。`umd` 目录下提供了两种版本：
 
-    - `core-js`
-    - 配置适当的 `@babel/preset-env` 和 `useBuiltIns` 设置
-    - 其他替代的 polyfill 实现
-    -
+  - `enum-plus.min.js`：对应的 EcmaScript 版本是 **`ES2020`**，适用于现代浏览器
+  - `enum-plus-legacy.min.js`：对应的 EcmaScript 版本是 **`ES2015`**，适用于旧版浏览器
 
-- **Node.js 兼容性**：enum-plus 需要至少 **`ES2016`** 的特性，兼容 Node.js `v7.x` 及以上版本。
+> **Polyfill 策略**：为了最小化包的体积，enum-plus 不包含任何 polyfill。如果需要支持旧版浏览器，可以自行引入以下工具：
