+# Client SDK
+
+The client SDK packages the license parsing, signature verification, and runtime health checks that every edge/desktop/embedded client needs so you don’t have to re-implement the security workflow in multiple codebases.
+
+## Quick Links
+
+- GitHub repository (README + samples + API docs): [https://github.com/cedar-v/license-manager-sdk-go](https://github.com/cedar-v/license-manager-sdk-go)
+- License structure reference: [`/en/guide/license-token-structure`](/en/guide/license-token-structure)
+
+> All hands-on content (installation, configuration, examples, changelog) lives inside the repository README so there is only one source of truth.
+
+## When to Use
+
+- Boot-time validation on standalone or edge deployments
+- Hybrid setups that exchange heartbeats with the License Manager service
+- Clients that need consistent error codes and logging for license enforcement
+
+Need a feature or found an issue? Open a discussion or issue directly in the repository to keep the conversation close to the source.

+# 客户端 SDK
+
+License Manager 提供可复用的客户端 SDK，涵盖许可证解析、验签与运行时校验等常见能力，避免你在各个项目中反复实现安全细节。
+
+## 快速入口
+
+- GitHub 仓库（含 README、示例与 API 说明）：[https://github.com/cedar-v/license-manager-sdk-go](https://github.com/cedar-v/license-manager-sdk-go)
+- 许可证结构参考：[`/guide/license-token-structure`](/guide/license-token-structure)
+
+> SDK 具体使用方法（安装、配置、代码示例等）请直接参考仓库 README；这里只保留索引，确保信息只维护一份。
+
+## 典型使用场景
+
+- 桌面/边缘客户端在启动阶段校验许可证合法性
+- 需要与 License Manager 云端做心跳或续期的混合部署
+- 通过统一错误码与日志追踪客户端授权状态
+
+如需在社群反馈功能需求或提 Issue，也欢迎直接在仓库参与讨论。
