 # Migrating from main to Open-Source v2-main
 
-## **Introduction**
+## Introduction
 
 Initially, Orbbec provided a **closed-source SDK — Orbbec SDK v1**, which formed the foundation of the [OrbbecSDK ROS2 Wrapper main branch](https://github.com/orbbec/OrbbecSDK_ROS2/tree/main). Although the ROS wrapper layer itself was open-source, it relied on a closed-source underlying SDK. This architecture imposed limitations on flexibility and hindered community-driven improvements.

 In October 2024, Orbbec released a major update: **OrbbecSDK ROS2 Wrapper v2**, which is entirely based on the open-source Orbbec SDK_v2. Compared to the legacy main branch (SDK v1.x), the v2-main branch (Orbbec SDK_v2.x) provides greater flexibility and scalability, while offering comprehensive support for all Orbbec USB products that comply with the UVC standard.The migration from main --> v2-main brings the following key advantages:

 # 从 main 分支迁移到开源 v2-main 分支
 
-## **引言**
+## 引言
 
 最初，奥比中光提供了一个**闭源 SDK — Orbbec SDK v1**，它构成了 [OrbbecSDK ROS2 Wrapper main 分支](https://github.com/orbbec/OrbbecSDK_ROS2/tree/main)的基础。虽然 ROS 封装层本身是开源的，但它依赖于闭源的底层 SDK。这种架构限制了灵活性，阻碍了社区驱动的改进。

 2024年10月，奥比中光发布了重大更新：**OrbbecSDK ROS2 Wrapper v2**，它完全基于开源的 Orbbec SDK_v2。与传统的 main 分支（SDK v1.x）相比，v2-main 分支（Orbbec SDK_v2.x）提供了更大的灵活性和可扩展性，同时为所有符合 UVC 标准的奥比中光 USB 产品提供全面支持。从 main --> v2-main 的迁移带来以下关键优势：
