 Spring Cloud Tencent包含了分布式应用微服务开发过程中所需的组件，基于 Spring Cloud 框架的开发者可以使用这些组件快速进行分布式应用的开发。
 
-在Spring Cloud Tencent的基础上，您只需要添加少量配置，就可以将 Spring Cloud 应用接入腾讯云微服务解决方案，通过腾讯云中间件来迅速搭建分布式应用系统。
-
 ## 主要功能
 
 * **服务注册与发现**：基于 Spring Cloud Common的标准进行微服务的注册与发现。
 * **服务路由与负载均衡**：基于 Ribbon 的接口标准，提供场景更丰富的动态路由以及负载均衡的能力。
 * **故障节点熔断**：提供故障节点的熔断剔除以及主/被动探测恢复的能力，保证分布式服务的可靠性。
 * **服务限流**：支持微服务被调接入层和网关主动调用的限流功能，保证后台微服务稳定性，可通过控制台动态配置规则，及查看流量监控数据。
-* **元数据传递**：支持网关和微服务之间的元数据传递。

 ### 如何引入依赖
 
 在 dependencyManagement 中添加如下配置，然后在 dependencies 中添加自己所需使用的依赖即可使用。
-与此同时，您需要注意Spring Cloud Tencent对应的Spring Cloud版本，进而对应到的Spring Boot版本。
-例如Spring Cloud Tencent的1.0.1.Hoxton.SR9对应Spring Cloud Hoxton版本，需要使用Spring Boot 2.3.x。

+# Spring Cloud Polaris Quickstart example
+
+## 样例简介
+
+本样例将介绍如何使应用快速接入Spring Cloud Tencent。
+
+## 使用说明
+
+### 修改配置
+
+修改bootstrap.yml，修改后配置如下所示。其中，${ip}和${port}为Polaris后端服务的IP地址与端口号。
+
+```yaml
+spring:
+  application:
+    name: EchoService
+  cloud:
+    polaris:
+      address: grpc://${ip}:${port}
+```
+
+### 启动样例
+
+#### 启动应用
+
+- IDEA启动
+
+找到 polaris-quickstart-example 项目的主类 EchoServiceApplication，执行 main 方法启动样例。
+
+- Maven打包启动
+
+在```spring-cloud-tencent-examples/polaris-quickstart-example```下执行
+
+```sh
+mvn clean package
+```
+
+然后找到生成的jar包，运行
+
+```
+java -jar ${app.jar}
+```
+
+启动应用，其中${app.jar}替换为对应的jar包名。
+
+### 验证
+
+#### HTTP调用
+
+```shell
+curl -L -X GET 'http://localhost:47080/quickstart/feign?msg=hello_world''
+```
+
+预期返回值：hello_world

+      address: grpc://${ip}:${port}
+```
+
+### Launching Example
+
+#### Launching Application
+
+- Start in IDEA
+
+Find main class EchoServiceApplication in project polaris-quickstart-example, and execute the main method.
+

+mvn clean package
+```
+
+find the generated fatjar, run:
+
+```
+java -jar ${app.jar}
+```
+
