+## Special Mentions
 
 Without the following people, this project would never have existed:
 
-  * [Dustin Krysak](https://wiki.ubuntu.com/bashfulrobot) - His support and feedback has been immense. More patience than you can throw a stick at (Not long now Dustin!).
-  * [Serge Zaitsev](https://github.com/zserge) - Creator of [Webview](https://github.com/zserge/webview) which Wails uses for the windowing.
-
-And without [these people](CONTRIBUTORS.md), it wouldn't be what it is today. A huge thank you to each and every one of you!

-Special Mentions:
-
-  * [Byron](https://github.com/bh90210) - At times, Byron has single handedly kept this project alive. Without his incredible input, we never would have got to v1.

+## 国际化
+
+[English](README.md) | 简体中文
+
+向 Go 程序提供 Web 接口的传统方法是通过内置 Web 服务器。Wails 提供了一种不同的方法：它提供了将 Go 代码和 Web
+前端都包装成单个二进制文件的能力。通过提供工具，可以很轻松的完成项目的创建、编译和打包。你所要做的就是发挥创意！
+
+官方文档可以在 [https://wails.app](https://wails.app) 中找到。

+
+## 安装
+
+Wails 使用 cgo 与原生渲染引擎结合，因此需要依赖一些平台的库以及 Go 的安装。基本要求是：
+
+- Go 1.16
+- npm
+
+<span id="nav-5-1"></span>
+
+### MacOS
+
+请确保已安装 xcode 命令行工具。这可以通过运行下面的命令来完成：
+
+`xcode-select --install`
+
+<span id="nav-5-2"></span>
+
+### Linux
+
+<span id="nav-5-2-1"></span>
+
+#### Debian/Ubuntu
+
+`sudo apt install libgtk-3-dev libwebkit2gtk-4.0-dev`
+
+_Debian: 8, 9, 10_
+
+_Ubuntu: 16.04, 18.04, 19.04_
+
+_也成功测试了: Zorin 15, Parrot 4.7, Linuxmint 19, Elementary 5, Kali, Neon_, Pop!\_OS
+
+<span id="nav-5-2-2"></span>
+
+#### Arch Linux / ArchLabs / Ctlos Linux
+
+`sudo pacman -S webkit2gtk gtk3`
+
+_也成功测试了: Manjaro & ArcoLinux_
+
+<span id="nav-5-2-3"></span>
+
+#### Centos
+
+`sudo yum install webkitgtk3-devel gtk3-devel`
+
+_CentOS 6, 7_
+
+<span id="nav-5-2-4"></span>
+
+#### Fedora
+
+`sudo yum install webkit2gtk3-devel gtk3-devel`
+
+_Fedora 29, 30_
+
+<span id="nav-5-2-5"></span>
+
+#### VoidLinux & VoidLinux-musl
+
+`xbps-install gtk+3-devel webkit2gtk-devel`
+
+<span id="nav-5-2-6"></span>
+
+#### Gentoo
+
+`sudo emerge gtk+:3 webkit-gtk`
+
+<span id="nav-5-3"></span>
+
+### Windows
+
+Windows 需要 GCC 和相关工具。 建议从 [http://tdm-gcc.tdragon.net/download](http://tdm-gcc.tdragon.net/download) 下载， 安装完成，您就可以开始了。
+
+<span id="nav-6"></span>
+
+## 安装
+
+**确保 Go modules 是开启的：GO111MODULE=on 并且 go/bin 在您的 PATH 变量中。**
+
+安装很简单，运行以下命令：
+
+<pre style='color:white'>
+go get -u github.com/wailsapp/wails/cmd/wails
+</pre>
+
+<span id="nav-7"></span>
+
+## 下一步
+
+建议在此时阅读 [https://wails.app](https://wails.app) 上面的文档.
+
+<span id="nav-8"></span>
+
+## 常见问题
+
+- 它是 Electron 的替代品吗?
+
+  取决于您的要求。它旨在使 Go 程序员可以轻松制作轻量级桌面应用程序或在其现有应用程序中添加前端。尽管 Wails 当前不提供对诸如菜单之类的原生元素的钩子，但将来可能会改变。
+
+- 这个项目针对的是谁?
+
+  希望将 HTML / JS / CSS 前端与其应用程序捆绑在一起的程序员，而不是借助创建服务并打开浏览器进行查看的方式。
+
+- 名字怎么来的?
+
+  当我看到 WebView 时，我想"我真正想要的是围绕构建 WebView 应用程序工作，有点像 Rails 对于 Ruby"。因此，最初它是一个文字游戏（Webview on
+  Rails）。碰巧也是我来自的 [国家](https://en.wikipedia.org/wiki/Wales) 的英文名字的同音。所以就是他了。

+# Build
+
+The build command processes the Wails project and generates an application binary. 
+
+## Usage
+
+`wails build <flags>`
+
+### Flags
+
+| Flag           | Details      | Default |
+| :------------- | :----------- | :------ |
+| -clean | Clean the bin directory before building   | |
+| -compiler path/to/compiler  | Use a different go compiler, eg go1.15beta1 | go |
+| -ldflags "custom ld flags" | Use given ldflags | | 
+| -o path/to/binary | Compile to given path/filename | |
+| -k | Keep generated assets | |
+| -package | Create a platform specific package | |
+| -production | Compile in production mode: -ldflags="-w -s" + "-h windows" on Windows | |
+| -tags | Build tags to pass to Go compiler (quoted and space separated) | |
+| -upx | Compress final binary with UPX (if installed) | |
+| -upxflags "custom flags" | Flags to pass to upx | |
+| -v int | Verbosity level (0 - silent, 1 - default, 2 - verbose) | 1 |
+| -delve | If true, runs delve on the compiled binary | false |
+
+## The Build Process
+
+The build process is as follows:
+
+  - The flags are processed, and an Options struct built containing the build context.
+  - The type of target is determined, and a custom build process is followed for target.
+
+### Desktop Target 
+
+  - The frontend dependencies are installed. The command is read from the project file `wails.json` under the key `frontend:install` and executed in the `frontend` directory. If this is not defined, it is ignored.
+  - The frontend is then built. This command is read from the project file `wails.json` under the key `frontend:install` and executed in the `frontend` directory. If this is not defined, it is ignored.
+  - The project directory is checked to see if the `build` directory exists. If not, it is created and default project assets are copied to it.
+  - An asset bundle is then created by reading the `html` key from `wails.json` and loading the referenced file. This is then parsed, looking for local Javascript and CSS references. Those files are in turn loaded into memory, converted to C data and saved into the asset bundle located at `build/assets.h`, which also includes the original HTML.
+  - The application icon is then processed: if there is no `build/appicon.png`, a default icon is copied. On Windows, an `app.ico` file is generated from this png. On Mac, `icons.icns` is generated.
+  - If there are icons in the `build/tray` directory, these are processed, converted to C data and saved as `build/trayicons.h`, ready for the compilation step.
+  - If there are icons in the `build/dialog` directory, these are processed, converted to C data and saved as `build/userdialogicons.h`, ready for the compilation step.
+  - If the `-package` flag is given for a Windows target, the Windows assets in the `build/windows` directory are processed: manifest + icons compiled to a `.syso` file (deleted after compilation).
+  - If we are building a universal binary for Mac, the application is compiled for both `arm64` and `amd64`. The `lipo` tool is then executed to create the universal binary.
+  - If we are not building a universal binary for Mac, the application is built using `go build`, using build tags to indicate type of application and build mode (debug/production).
+  - If the `-upx` flag was provided, `upx` is invoked to compress the binary. Custom flags may be provided using the `-upxflags` flag.
+  - If the `package` flag is given for a non Windows target, the application is bundled for the platform. On Mac, this creates a `.app` with the processed icons, the `Info.plist` in `build/darwin` and the compiled binary.

+
+### Flags
+
+| Flag           | Details      | Default |
+| :------------- | :----------- | :------ |
+| -compiler path/to/compiler  | Use a different go compiler, eg go1.15beta1 | go |

+| -loglevel  | Loglevel to pass to the application - Trace, Debug, Info, Warning, Error | Debug |
+
+## How it works
+
+The project is built using a special mode that starts a webserver and starts listening to port 34115. When the frontend project is run independently, so long as the JS is wrapped with the runtime method `ready`, then the frontend will connect to the backend code via websockets. The interface should be present in your browser, and you should be able to interact with the backend as you would in a desktop app.

+# Generate
+
+The `generate` command provides the ability to generate various Wails related components.
+
+## Usage
+
+`wails generate [subcommand] [options]`
+
+## Template
+
+`wails generate template -name <name> [-frontend] [-q]`
+
+Generate a starter template for you to customise.
+
+| Flag           | Details      | 
+| :------------- | :----------- | 
+| -frontend  | Copies all the files from the current directory into the template's `frontend` directory. Useful for converting frontend projects created by boilerplate generators. |
+| -q | Suppress output |
