-React Native is not just for Android and iOS - there are community-supported projects that bring it to other platforms, such as:
+React Native不仅适用于 Android 和 iOS - 还有社区支持的项目将其应用于其他平台，例如：
 
-- [React Native Windows](https://github.com/Microsoft/react-native-windows) - React Native support for Microsoft's Universal Windows Platform (UWP) and the Windows Presentation Foundation (WPF)
-- [React Native DOM](https://github.com/vincentriemer/react-native-dom) - An experimental, comprehensive port of React Native to the web. (Not to be confused with [React Native Web](https://github.com/necolas/react-native-web), which has different goals)
-- [React Native Desktop](https://github.com/status-im/react-native-desktop) - A project aiming to bring React Native to the Desktop with Qt's QML. A fork of [React Native Ubuntu](https://github.com/CanonicalLtd/react-native/), which is no longer maintained.
-- [React Native macOS](https://github.com/ptmt/react-native-macos) - An experimental React Native fork targeting macOS and Cocoa
-- [React Native tvOS](https://github.com/react-native-community/react-native-tvos) - adaptation of React Native for Apple tvOS
-- [alita](https://github.com/areslabs/alita) - An experimental, comprehensive port of React Native to mini-program(微信小程序).
-- [Proton Native](https://github.com/kusti8/proton-native) - A wrapper for React Native, using Qt to target Linux, MacOS, and Windows.
+- [React Native Windows](https://github.com/Microsoft/react-native-windows) - React Native 支持 Microsoft Universal Windows Platform (UWP) 和 Windows Presentation Foundation (WPF)
+- [React Native DOM](https://github.com/vincentriemer/react-native-dom) - 一个实验性的、全面的 React Native 到 web 的端口。（不要与[React Native Web](https://github.com/necolas/react-native-web)混淆，两者目标不同）
+- [React Native Desktop](https://github.com/status-im/react-native-desktop) - 一个旨在通过 Qt 的 QML 将 React Native 带到桌面的项目。[React Native Ubuntu](https://github.com/CanonicalLtd/react-native/)的一个分支，已不再维护。
+- [React Native macOS](https://github.com/ptmt/react-native-macos) - 针对 macOS 和 Cocoa 的实验性 React Native 分支
+- [React Native tvOS](https://github.com/react-native-community/react-native-tvos) - 为 Apple tvOS 适配 React Native
+- [alita](https://github.com/areslabs/alita) - 一个实验性的、综合性的 React Native 到微信小程序的端口
+- [Proton Native](https://github.com/kusti8/proton-native) - React Native 的封装器，使用 Qt 面向 Linux、MacOS 和 Windows

-Right now the process of creating a React Native platform from scratch is not very well documented - one of the goals of the upcoming re-architecture ([Fabric](https://facebook.github.io/react-native/blog/2018/06/14/state-of-react-native-2018)) is to make maintaining a platform easier.
+目前，从头开始创建 React Native 平台的过程并没有很好的记录——即将到来的全新架构（[Fabric](https://facebook.github.io/react-native/blog/2018/06/14/state-of-react-native-2018)）的目标之一是使平台的维护更容易。
 
-### Bundling

-As of React Native 0.57 you can now register your React Native platform with React Native's JavaScript bundler, [Metro](https://facebook.github.io/metro/). This means you can pass `--platform example` to `npx react-native bundle`, and it will look for JavaScript files with the `.example.js` suffix.
+从 React Native 0.57 开始，你现在可以使用 React Native 的 JavaScript 打包器[Metro](https://facebook.github.io/metro/)注册你的 React Native 平台。这意味着你可以将`--platform example`传递给`npx react-native bundle`，它会查找带有`.example.js`后缀的 JavaScript 文件。
 
-To register your platform with RNPM, your module's name must match one of these patterns:
+要将你的平台注册到 RNPM，模块名称必须与以下模式之一匹配：
 
-- `react-native-example` - It will search all top-level modules that start with `react-native-`
-- `@org/react-native-example` - It will search for modules that start with `react-native-` under any scope
-- `@react-native-example/module` - It will search in all modules under scopes with names starting with `@react-native-`
+- `react-native-example` - 它会搜索所有以`react-native-`开头的顶级模块
+- `@org/react-native-example` - 它会在所有范围内搜索以`react-native-`开头的模块
+- `@react-native-example/module` - 它会在名称以`@react-native-`开头的范围内搜索所有模块
