+# 贡献指南
+
+Language: [English](CONTRIBUTING.md) | 简体中文
+
+首先，感谢您考虑为 `dio` 项目做出贡献！像这样的开源项目得以成长和繁荣，多亏了像您这样的贡献者。无论您是在修复错误、添加新功能、改进文档还是报告问题，每一份贡献都是宝贵和值得赞赏的。
+
+本文档提供了一些指南，以帮助确保您的贡献尽可能有效。在提交您的贡献之前，请花一点时间阅读这些指南。
+
+请记住，每个为这个项目做出贡献的人都需要遵循我们的行为准则。这有助于确保所有贡献者的积极和包容环境。
+
+再次感谢您的贡献，我们期待看到您将为 `dio` 项目带来什么！
+
+## 创建好的工单
+
+> [!TIP]
+> 在创建新问题之前，搜索已有的工单和拉取请求以避免重复是一个好习惯。
+
+### 错误报告
+
+报告错误时，请包括以下信息：
+
+1. **标题**：简短描述性的错误标题。
+2. **包**：指定有问题的包。
+3. **版本**：您正在使用的包版本。
+4. **操作系统**：出现问题的操作系统。
+5. **适配器**：指定使用的适配器。
+6. **`flutter doctor -v` 的输出**：使用 Flutter 时需要。
+7. **Dart 版本**：您使用的 Dart 版本。
+8. **重现步骤**：详细步骤说明如何重现错误。
+9. **预期结果**：您期望发生的事情。
+10. **实际结果**：实际发生的事情。包括日志、屏幕截图或任何其他相关信息。
+
+### 功能请求
+
+请求新功能时，请包括以下信息：
+
+1. **标题**：功能请求的简短描述性标题。
+2. **请求声明**：描述您认为 `dio` 项目能解决但目前没有解决的问题。
+3. **解决方案头脑风暴**：分享您的想法，关于如何解决问题。如果您没有特定的解决方案，那也没关系！
+
+> [!TIP]
+> 记住，您提供的信息越多，我们就越容易理解和解决问题。感谢您的贡献！
+> 请避免评论旧的、已关闭的工单。如果旧问题似乎与您的问题有关但并未完全解决您的问题，最好开一个新工单并引用旧的。
+
+## 开发
+
+此项目使用 [Melos](https://github.com/invertase/melos) 管理单体仓库和大多数任务。Melos 是一个为 Dart 和 Flutter 的多包项目优化工作流的工具。有关如何使用 Melos 的更多信息，请参阅 [Melos 文档](https://melos.invertase.dev)。
+
+### 设置
+
+开始之前，您需要全局安装 Melos：
+
+```bash
+dart pub global activate melos
+```
+
+在安装 Melos 后，可以克隆仓库并安装依赖项：
+
+```bash
+git clone https://github.com/cfug/dio.git
+cd dio
+melos bootstrap
+```
+
+## 提交更改
+
+在以拉取请求提交您的更改之前，请确保格式化和分析您的代码并运行所有测试。以下是您应该了解的主要 melos 脚本：
+
+### 代码质量
+
+要格式化（和修复）所有包，请运行：
+```bash
+melos run format
+# 或者
+melos run format:fix
+```
+
+要分析所有包，请运行：
+```bash
+melos run analyze
+```
+
+### 测试
+
+要运行所有测试，请使用：
+```bash
+melos run test
+```
+
+可以使用适当的脚本运行单个测试目标：
+```bash
+melos run test:vm
+melos run test:web
+melos run test:web:chrome
+melos run test:web:firefox
+```

+When reporting a bug, please include the following information:
+
+1. **Title**: A brief, descriptive title for the bug.
+2. **Package**: Specify which package has the problem.
+3. **Version**: The version of the package you are using.
+4. **Operating System**: The OS on which the problem occurs.
+5. **Adapter**: Specify which adapter(s) are used.
+6. **Output of `flutter doctor -v`**: Required when used with Flutter.
+7. **Dart Version**: The version of Dart you are using.
+8. **Steps to Reproduce**: Detailed steps on how to reproduce the bug.
+9. **Expected Result**: What you expected to happen.

+
+### Feature Requests
+
+When requesting a new feature, please include the following information:
+
+1. **Title**: A brief, descriptive title for the feature request.
+2. **Request Statement**: Describe the problem that you believe the `dio` project could solve but currently doesn't.
+3. **Solution Brainstorm**: Share your ideas on how the problem could be solved. If you don't have a specific solution in mind, that's okay too!
+
+> [!TIP]
+> Remember, the more information you provide, the easier it is for us to understand and address the issue. Thank you for your contributions!
+> Please refrain from commenting on old, closed tickets. If an old issue seems related but doesn't fully address your problem, it's best to open a new ticket and reference the old one instead.
+
+## Development
+
+This project uses [Melos](https://github.com/invertase/melos) to manage the mono-repo and most tasks. Melos is a tool that optimizes the workflow for multi-package Dart and Flutter projects. For more information on how to use Melos, please refer to the [Melos documentation](https://melos.invertase.dev).
+
+
+### Setup
+
+To get started, you'll need to install Melos globally:
+
+```bash
+dart pub global activate melos
+```
+
+After installing Melos, you can clone the repository and install the dependencies:
+
+```bash
+git clone https://github.com/cfug/dio.git
+cd dio
+melos bootstrap
+```
+
+## Submitting changes
+
+Before submitting your changes as a pull request, please make sure to format and analyze your and run the all tests. Here are the main melos scripts you should be aware of:
+
+### Code quality
+
+To format (and fix) all packages, run: 
+```bash
+melos run format
+# OR
+melos run format:fix
+```
+
+To analyze all packages, run: 
+```bash
+melos run analyze
+```
+
+### Testing
+
+To run all tests, use: 
+```bash
+melos run test
+```
+
+Individual test targets can be run with the appropriate scripts:
+```bash
+melos run test:vm
+melos run test:web
+melos run test:web:chrome
+melos run test:web:firefox
+```
