 * **Toolchain**: Includes an extensive toolchain, such as the code generation of cache, the lint tool, and so forth.
 
 ## Features
-* APIs: The communication protocol is based on the HTTP/gRPC through the definition of Protobuf.
-* Errors: Both the definitions of error code and the handle interfaces of code generation for tools are defined by the Enum of the Protobuf.
-* Metadata: In the protocol of HTTP/gRPC, the transmission of service atomic information are formalized by the Middleware.
-* Config: Multiple data sources are supported for configurations and integrations such that dynamic configurations are offered through the manner of *Atomic* operations.
-* Logger: The standard log interfaces ease the integration of the third-party log libs and logs are collected through the *Fluentd*.
-* Metrics: *Prometheus* integrated by default. Furthermore, with the uniform metric interfaces, you can implement your own metric system more flexible.
-* Tracing: The OpenTelemetry is conformed to achieve the tracing of microservices chains.
-* Encoding: The selection of the content encoding is automatically supported by Accept and Content-Type.
-* Transport: The uniform plugins for Middleware are supported by HTTP/gRPC.
-* Registry: The interfaces of the centralized registry is able to be connected with various other centralized registries through plug-ins.

-* Errors：通过 Protobuf 的 Enum 作为错误码定义，以及工具生成判定接口；
-* Metadata：在协议通信 HTTP/gRPC 中，通过 Middleware 规范化服务元信息传递；
-* Config：支持多数据源方式，进行配置合并铺平，通过 Atomic 方式支持动态配置；
-* Logger：标准日志接口，可方便集成三方 log 库，并可通过 fluentd 收集日志；
-* Metrics：统一指标接口，可以实现各种指标系统，默认集成 Prometheus；
-* Tracing：遵循 OpenTelemetry 规范定义，以实现微服务链路追踪；
-* Encoding：支持 Accept 和 Content-Type 进行自动选择内容编码；
