 ## 简介

 CrossDesk 是一个轻量级的跨平台远程桌面软件，支持 Web 端控制远程设备。

 CrossDesk 是 [MiniRTC](https://github.com/kunkundi/minirtc.git) 实时音视频传输库的实验性应用。MiniRTC 是一个轻量级的跨平台实时音视频传输库。它具有网络透传（[RFC5245](https://datatracker.ietf.org/doc/html/rfc5245)），视频软硬编解码（H264/AV1），音频编解码（[Opus](https://github.com/xiph/opus)），信令交互，网络拥塞控制，传输加密（[SRTP](https://tools.ietf.org/html/rfc3711)）等基础能力。

 ### Windows 服务（CrossDesk Service）

 CrossDesk 在 Windows 平台提供本地辅助服务 **CrossDesk Service**，服务名为 `CrossDeskService`。该服务用于锁屏、登录界面和安全桌面等受保护场景下的远程控制增强能力，包括：
+
 - 上报远端当前是否处于锁屏、登录、凭据输入或安全桌面状态；
 - 支持从控制端发送 `Ctrl+Alt+Del`（SAS）；
 - 在锁屏、登录和安全桌面阶段转发键盘、鼠标输入。

 如果是手动编译或手动部署 Windows 版本，请确保 `CrossDesk.exe`、`crossdesk_service.exe` 和 `crossdesk_session_helper.exe` 位于同一目录。安装或卸载服务需要使用管理员权限打开 PowerShell：
-```

+## Introduction

 CrossDesk is a lightweight cross-platform remote desktop software.

 CrossDesk is an experimental application of [MiniRTC](https://github.com/kunkundi/minirtc.git), a lightweight cross-platform real-time audio and video transmission library. MiniRTC provides fundamental capabilities including network traversal ([RFC5245](https://datatracker.ietf.org/doc/html/rfc5245)), video software/hardware encoding and decoding (H264/AV1), audio encoding/decoding ([Opus](https://github.com/xiph/opus)), signaling interaction, network congestion control, and transmission encryption ([SRTP](https://tools.ietf.org/html/rfc3711)).

 ### Windows Service (CrossDesk Service)
+
 CrossDesk provides a local helper service on Windows named **CrossDesk Service**. Its service name is `CrossDeskService`. The service improves remote control in protected Windows states such as the lock screen, sign-in UI, credential UI, and secure desktop. It provides:
+
 - Remote status reporting for lock screen, sign-in, credential, and secure desktop states.
 - Remote `Ctrl+Alt+Del` (SAS) delivery.
 - Keyboard and mouse input forwarding while the remote Windows device is on the lock screen, sign-in UI, or secure desktop.
@@ -65,7 +79,8 @@ CrossDesk provides a local helper service on Windows named **CrossDesk Service**
 The Windows installer bundles `crossdesk_service.exe` and `crossdesk_session_helper.exe`, then registers the service as an on-demand Windows service during installation. When the CrossDesk client starts, it tries to start the installed service automatically. When no CrossDesk client process is running on the machine, the service exits automatically. Uninstalling the client also stops and removes the service.

 For manual Windows builds or deployments, make sure `CrossDesk.exe`, `crossdesk_service.exe`, and `crossdesk_session_helper.exe` are placed in the same directory. Open PowerShell with administrator privileges to install or uninstall the service:
-```
