+# SIG Template
+English | [简体中文](./sig_devboard_cn.md)
+
+Note: The content of this SIG follows the convention described in OpenHarmony's PMC Management Charter [README](/zh/pmc.md).
+
+## SIG group work objectives and scope
+
+
+To increase the number of third-party boards of the OpenHarmony OS, the device SIG 
+provides easy porting guide that board manufacturers could follow to contribute 
+their codes to the community easily. The more important thing is actively cooperating 
+with board manufacturers to enhance the OpenHarmony ecosystem.
+
+### Scope
+
+- Easy Porting Requirements
+
+Proposes easy porting requirements that all OpenHarmony projects, not only kernel and building project, should 
+develop.
+
+- Porting and Contributing Guidelines
+
+Guides board manufacturers to contribute their codes to the community.
+
+- Demo Projects
+
+Creates demo projects, hi3516/hi3518/hi3861, for others to follow.
+
+- Expanding Ecosystems
+
+Actively cooperates with board manufacturers.
+
+### The repository 
+- project name:
+  - device_st: https://gitee.com/openharmony-sig/device_st

+# SIG组
+简体中文 | [English](./sig_driver.md)
+
+说明：本SIG的内容遵循OpenHarmony的PMC管理章程 [README](/zh/pmc.md)中描述的约定。
+
+## SIG组工作目标和范围
+
+### 工作目标
+为了增加OpenHarmony OS所支持的三方单板数量，Device SIG不仅需要提高系统的易移植性，包括内核和编译构建系统的易移植性需求，
+提供三方单板移植手册，创建移植样例工程；更为重要的是，需要扩展生态，与单板厂商进行合作，协助他们贡献他们的代码
+上库。
+
+### 工作范围
+
+- 易移植性需求
+
+提出移植性需求，所有的OpenHarmony项目都需要支持，不仅是内核和编译项目
+
+- 移植和贡献规范
+
+指导单板厂商贡献他们的代码到社区
+
+- 样例工程
+
+创建三方单板的样例工程，例如hi3516、hi3518和hi3861，给其他单板厂商来参考
+
+- 生态拓展
+
+积极与单板厂商进行洽谈合作
+
+## 代码仓
+- 代码仓地址：
+  - device_st: https://gitee.com/openharmony-sig/device_st
+  - vendor_huawei_minidisplay_demo: https://gitee.com/openharmony-sig/vendor_huawei_minidisplay_demo
