+这款完全用 Rust 构建的 AiR 提供了惊人的速度和效率！
+
+AiR 拥有两个主要功能：准确的翻译和无缝的文本重写，旨在极大地提升您的生产力。
+
+AiR 是非母语者的绝佳助手，能够自动修正错误并润色语言，使其听起来像母语使用者。
+
+更多精彩功能即将推出！
+
+[English](README.md) ｜ [中文](README-zh-CN.md)

+### 安装
+#### 从源代码构建
+```sh
+# 安装 Rust。
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --default-toolchain stable
+
+# 克隆代码库。
+git clone https://github.com/hack-ink/air
+cd air
+
+# 构建项目后，二进制文件将位于 `target/release/air`。
+cargo build --release
+
+# 如果您是 macOS 用户并且想拥有一个 `AiR.app`，请运行以下命令。
+# 安装 `cargo-bundle` 将二进制文件打包成应用程序。
+cargo install cargo-bundle
+# 构建应用程序后，它将位于 `target/release/bundle/osx/AiR.app`。
+cargo bundle --release
+```
+
+#### 下载预构建二进制文件
+- **macOS**
+  - 从 [GitHub Releases](https://github.com/hack-ink/air/releases/latest) 下载最新的预构建二进制文件。
+- **Windows**
+  - 即将推出
+- **Unix**
+  - 已计划
+
+### 配置
+#### 打开来自未识别开发者的 Mac 应用程序（仅限 macOS）
+当您第一次打开应用时，您会看到以下消息：
+
+`“AiR” 无法打开，因为无法验证开发者。`
+
+由于我不是认证开发者，您需要允许该应用在您的 Mac 上运行。
+
+请请我喝杯咖啡，以便我能获得一个 Apple 开发者证书。 😄
+
+1. `打开“系统偏好设置” -> “隐私与安全性”。`
+2. `请向下滚动到 ‘“AiR” 因不是来自已识别的开发者而被阻止使用’ 部分。`
+3. `点击 “仍然打开”。`
+
+相关资源：
+- [打开来自未识别开发者的 Mac 应用程序 (support.apple.com)](https://support.apple.com/en-hk/guide/mac-help/mh40616/mac)
+- [如何打开来自未识别开发者的 Mac 应用程序 (macworld.com)](https://www.macworld.com/article/672947/how-to-open-a-mac-app-from-an-unidentified-developer.html)
+
+#### 获取系统辅助功能权限（仅限 macOS）
+要控制键盘并使用系统剪贴板进行数据读写，
+AiR 必须获得系统辅助功能权限。
+
+1. `打开 “系统设置” -> “隐私与安全” -> “辅助功能”。`
+2. `点击 “+” 按钮，然后添加 “AiR.app” 或 “air” 二进制文件。`
+
+#### 设置
+你可以通过导航到 “设置” 面板来配置设置。
+
+- 通用
+  - 字体大小
+  - 失去焦点时隐藏：当应用程序失去焦点时隐藏它。
+  - 激活的功能：使用非直接功能时启用的功能。
+- AI
+  - API 基础：AI API 的基本 URL。确保不要忘记 `v1` 部分。（例如：https://api.openai.com/v1）。
+  - API 密钥：AI API 密钥。
+  - 模型：AI 模型。
+  - 温度：人工智能的不可预测性。
+- 翻译
+  - 语言 A：您希望从/向 B 翻译的语言。
+  - 语言 B：您希望从/向 A 翻译的语言。
+- 快捷键
+  - 重写​
+  - 直接重写​
+  - 翻译​
+  - 直接翻译
+- 开发
+  - 日志级别
+
+AiR目前正在进行大量开发，并非所有设置都会在用户界面中始终可用。
+
+然而，所有设置始终可以在设置文件中找到。
+
+设置文件的位置因操作系统而异。
+- `~/Library/Application\ Support/AiR/setting.toml` (macOS)
+- `C:\Users\<username>\AppData\Roaming\AiR\setting.toml` (Windows)
+- `~/.config/AiR/setting.toml` (Unix)
+
+#### 交互
+在输入区域中键入文本，然后在 macOS 上按 `META+ENTER` 或在其他操作系统上按 `CTRL+ENTER` 以触发相应的功能。
+
+您还可以选择文本并使用快捷键直接对选定的文本应用相应的功能。
+
+### 更新
+正在开发自动更新功能。
+
+目前，您可以通过重复安装步骤手动更新应用程序。
+
+#### 重新获得系统访问权限（仅适用于macOS）
+1. `按照 “获取系统访问权限” 部分找到 “AiR.app” 或 “air” 二进制文件。`
+2. `点击 “-” 按钮以移除现有权限，然后点击 “+” 按钮重新添加权限。`

+#### Build from Source
+```sh
+# Install Rust.
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --default-toolchain stable
+
+# Clone the repository.
+git clone https://github.com/hack-ink/air
+cd air
+
+# Build the project, and the binary will be available at `target/release/air`.
+cargo build --release
+
+# If you are a macOS user and want to have a `AiR.app`, run the following command.
+# Install `cargo-bundle` to package the binary into an app.
+cargo install cargo-bundle
+# Build the app, and the it will be available at `target/release/bundle/osx/AiR.app`.
+cargo bundle --release
+```
+
+#### Download Pre-built Binary
+- **macOS**
+  - Download the latest pre-built binary from [GitHub Releases](https://github.com/hack-ink/air/releases/latest).
+- **Windows**
+  - Coming Soon
+- **Unix**
+  - Planed
+
+### Configuration
+#### Open a Mac app from an unidentified developer (macOS only)
+When you open the app for the first time, you'll see the following message:
+
+`"AiR" cannot be opened because the developer cannot be verified.`
+
+Since I'm not an identified developer, you need to allow the app to run on your Mac.
+
+Buy me a coffee so I can get an Apple Developer Certificate. 😄
+
+1. `Open "System Preferences" -> "Privacy & Security".`
+2. `Scroll down to the '"AiR" was blocked from use because it is not from an identified developer.' section.`
+3. `Click "Open Anyway".`
+
+Relate resources:
+- [Open a Mac app from an unidentified developer (support.apple.com)](https://support.apple.com/en-hk/guide/mac-help/mh40616/mac)
+- [How to open a Mac app from an unidentified developer (macworld.com)](https://www.macworld.com/article/672947/how-to-open-a-mac-app-from-an-unidentified-developer.html)
+
+#### Gain System Accessibility Permission (macOS only)
+To control the keyboard and use the system clipboard for reading and writing data,
+AiR must obtain system accessibility permissions.
+
+1. `Open "System Settings" -> "Privacy & Security" -> "Accessibility".`
+2. `Click the "+" button and add the "AiR.app" or "air" binary.`
+
+#### Setting
+You can configure the settings by navigating to the "Settings" panel.
+
+- General
+  - Font Size
+  - Hide on Lost Focus: Hide the app when it loses focus.
+  - Active Function: The active function when using non-directly functions.
+- AI
+  - API Base: The base URL of the AI API. It's crucial to ensure you don't forget the `v1` part. (e.g., https://api.openai.com/v1).
+  - API	Key: The AI API key.
+  - Model: The AI model.
+  - Temperature: The unpredictability of AI.
+- Translation
+  - Language A: The language you want to translate from/to B.
+  - Language B: The language you want to translate from/to A.
+- Hotkey
+  - Rewrite
+  - Rewrite Directly
+  - Translate
+  - Translate Directly
+- Development
+  - Log Level
+
+AiR is currently under heavy development, and not all settings are always available in the user interface.
+
+However, all settings can always be found in the settings file.
+
+The location of the settings file varies depending on the OS.
+- `~/Library/Application\ Support/AiR/setting.toml` (macOS)
+- `C:\Users\<username>\AppData\Roaming\AiR\setting.toml` (Windows)
+- `~/.config/AiR/setting.toml` (Unix)
+
+#### Interaction
+Type the text in the input area and press `META+ENTER` on macOS or `CTRL+ENTER` on other OS to trigger the corresponding function.
+
+You can also select text and use hotkeys to directly apply the corresponding function to the selected text.
+
+### Update
+An automatic update feature is under development.
+
+For now, you can manually update the app by repeating the installation steps.
+
+#### Re-gain System Accessibility Permission (macOS only)
+1. `Follow the "Gain System Accessibility Permission" section to locate the "AiR.app" or "air" binary.`
+2. `Click the "-" button to remove the existing permission, then click the "+" button to re-add it.`
+

-## Architecture
-Built upon [egui](https://github.com/emilk/egui), a fast and cross-platform GUI toolkit written in pure Rust.
+- **Components**
+  - Provides the basic data structures and functions used by other parts of the program.
+  - Component should be static, don't include any mutable state.
+- **OS**
+  - Provides wrapped APIs to interact with the OS.
+  - Differences between OS should be addressed here and presented in a summarized, abstract manner.
+- **Services**
+  - Provides background tasks ability to run independently of the UI.
+  - Service has one or more requirements for a cache component to conserve system resources, perform frequent checks or updates, and handle time-sensitive tasks.
+  - Service related to UI settings should provide a hot reload function so that when a setting is changed on UI, the changes are applied immediately.
+  - Service should include an abort function to stop the service, and it should be called when exiting the program. to prevent it from stalling.
+- **State**
+  - Provides mutability that can be synchronized and shared throughout the entire program.
+  - State should be `Arc<parking_lot::Mutex/RwLock<_>>` or `Arc<std::sync::atomic::Atomic*>`.
+- **UI**
+  - Provides the interaction ability of other parts for users.
+
 
-### Components
-- **Static**: These items are static and are used by other parts of the application.
+## Support Me
+If you find this project helpful and would like to support its development, you can buy me a coffee!
 
-### OS
-- **Interaction**: Provides wrapped APIs to interact with the operating system.
+Your support is greatly appreciated and motivates me to keep improving this project.
 
-### Services
-- **Background Processes**: These items are time-sensitive and require frequent checking or updating. They will be spawned as separate threads and run in the background.
