 ## Introduction
 
-xgen is a library written in pure Go providing a set of functions that allow you to parse XSD (XML schema definition) files. This library needs Go version 1.10 or later. The full API docs can be seen using go's built-in documentation tool, or online at [godoc.org](https://godoc.org/github.com/xuri/xgen).

+
+## Introduction
+
+xgen 是 Go 语言编写的 XSD (XML Schema Definition) 工具基础库。使用本基础库要求使用的 Go 语言为 1.10 或更高版本，完整的 API 使用文档请访问 [go.dev](https://pkg.go.dev/github.com/xuri/xgen?tab=doc)。
+
+`xgen` 命令可将 XML 模式定义文件编译为多语言类型或类声明的代码。
+
+首先安装命令行工具:
+
+```text
+go get github.com/xuri/xgen
+```
+
+下面的命令将遍历 `xsd` 目录中的 XML 模式定义文件，并在 `output` 目录中生成 Go 语言结构体声明代码。
+
+```text
+$ xgen -i /path/to/your/xsd -o /path/to/your/output -l Go
+```
+
+Usage:
+
+```text
+$ xgen [<flag> ...] <XSD file or directory> ...
+   -i <path> 指定存放 XML 模式代码文件的输入路径
+   -o <path> 指定输出代码目录
+   -p        指定生成代码所属包名称
+   -l        指定生成类型或类声明代码语言类型 (Go/C/Java/Rust/TypeScript)
+   -h        查看此帮助信息并退出
+   -v        查看版本号并退出
+```
+
+## XSD (XML Schema Definition)
+
+XSD 是万维网联盟 ([W3C](https://www.w3.org)) 推荐的标准，它指定了在可扩展标记语言 ([XML](https://www.w3.org/TR/xml/)) 文档中描述元素的规范。开发者可以使用它来验证文档中的每个项目内容，并可以检查它是否符合放置元素的说明。
+
+XSD 是一种分离于 XML 本身的模式语言，可用于表示 XML 文档所必须遵循的一组规则，并可根据该规则进行模式有效性验证。
+
+## 社区合作
+
+欢迎您为此项目贡献代码，提出建议或问题、修复 Bug 以及参与讨论对新功能的想法。XML 符合标准：[XML Schema Part 1: Structures Second Edition](https://www.w3.org/TR/xmlschema-1/).
