+
+## SIG group work objectives and scope
+
+
+### Objectives of SIG
+
+RISC-V SIG aims to build a RISC-V ecosystem for OpenHarmony, provide instructions to build software, maintain supports for RISC-V devices, and enable security capabilities like TEE on RISC-V.
+RISC-V SIG will promote more developers to involve in developing OpenHarmony on RISC-V.
+
+### Scope of SIG
+
+- Maintain supported RISC-V devices for OpenHarmony
+
+The SIG will continuously port and maintain OpenHarmony to support different RISC-V devices.
+
+- RISC-V Security
+
+The SIG will enable TEE capability for OpenHarmony on RISC-V based on Penglai Enclave.
+
+- Build Ecosystems
+
+The SIG will actively cooperate with schools and end-users to promote the usage of OpenHarmony on RISC-V devices.
+
+
+### The repository

+
+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
+
+RISC-V 是一个免费开源的指令集（ISA）。围绕RISC-V的软硬件生态都在快速完善。
+RISC-V SIG 组旨在构建围绕OpenHarmony的软硬件生态，提供RISC-V的软件包和系统构建等指导，并维护对RISC-V设备的支持，使能RISC-V场景下的安全等能力。
+RISC-V SIG将推动对 RISC-V OpenHarmony感兴趣的开发者能够参与到开源系统开发中活动中来。
+
+
+### 工作范围
+
+- 维护OpenHarmony在RISC-V设备上的使用
+
+SIG将不断更新（移植）和维护OpenHarmony能够支持的RISC-V设备。
+
+- RISC-V 安全能力
+
+SIG将结合蓬莱RISC-V TEE使能OpenHarmony在RISC-V场景下的安全能力。
+
+- 生态扩展
+
+积极与高校和相关客户合作，推动OpenHarmony在RISC-V环境下的应用。
