-### Version Standard
-
-We use a version policy related to Spring Cloud's major version number.
-
-Project version includes ```${MAJOR_VERSION}.${MINOR_VERSION}.${PATCH_VERSION}-${CORRESPONDING_MAJOR_VERSION_OF_SPRING_CLOUD}.${CORRESPONDING_MINOR_VERSION_OF_SPRING_CLOUD}-${RELEASE_TYPE}```.
-```${MAJOR_VERSION}```, ```${MINOR_VERSION}```, ```${PATCH_VERSION}``` are in numbers starting from 0.
-```${CORRESPONDING_MAJOR_VERSION_OF_SPRING_CLOUD}``` is the same as the major version number of Spring Cloud, like Hoxton, Greenwich. ```${CORRESPONDING_MINOR_VERSION_OF_SPRING_CLOUD}``` is the same as the major version number of Spring Cloud, like RS9.
-```${RELEASE_TYPE}``` is like RELEASE or RC currently. Actually, the RELEASE version does not add a release type in the version, and the RS version will add a suffix and start from RC0.
-
-For example: 1.2.0-Hoxton.SR9-RC0

-## 版本号规范
-
-采取与Spring Cloud大版本号相关的版本策略。
-
-项目的版本号格式为 ```大版本号.小版本号.补丁版本号-对应Spring Cloud的大版本号.对应Spring Cloud的小版本号-发布类型``` 的形式。
-大版本号、小版本号、补丁版本号的类型为数字，从 0 开始取值。
-对应Spring Cloud的大版本号为Spring Cloud提供的英文版本号，例如Hoxton、Greenwich等。对应Spring Cloud的小版本号为Spring Cloud给出的小版本号，例如 RS9 等。
-发布类型目前包括正式发布和发布候选版（RC）。在实际的版本号中，正式发布版不额外添加发布类型，发布候选版将添加后缀，并从 RC0 开始。
 
-示例：1.2.0-Hoxton.SR9-RC0

 ## Introduction
 
-Spring Cloud Tencent contains components distributed micro-service applications need during developing phase, developers that built their key architectures based on Spring Cloud can use these components
+Spring Cloud Tencent is a one-stop microservice solution developed and maintained by Tencent.
+
+Spring Cloud Tencent implements the Spring Cloud standard microservice SPI, so developers can quickly develop Spring Cloud cloud-native distributed applications based on Spring Cloud Tencent.
+
+The core of Spring Cloud Tencent relies on Tencent's open-source one-stop service discovery and governance platform [Polaris](https://github.com/polarismesh/polaris) to realize various distributed microservice scenarios.
+
+- [Polaris Github home page](https://github.com/polarismesh/polaris)
+- [Polaris official website](https://polarismesh.cn/)
+
+The capabilities provided by Spring Cloud Tencent include but are not limited to:
+
+- Service registration and discovery
+- Dynamic configuration management
+- Service Governance
+  - Service current limit
+  - Service circuit breaker
+  - Service routing
+  - ...
+- Label transparent transmission
+
+## Use Guide
+
+All the components of Spring Cloud Tencent have been uploaded to the Maven central repository, just need to introduce dependencies.
+
+For example:
+
+````  
+<!-- add spring-cloud-tencent bom  -->
+<dependencyManagement>
+    <dependencies>
+        <dependency>
+            <groupId>com.tencent.cloud</groupId>
+            <artifactId>spring-cloud-tencent-dependencies</artifactId>
+            <!--version number-->
+            <version>${version}</version>
+            <type>pom</type>
+            <scope>import</scope>
+        </dependency>
+    </dependencies>
+</dependencyManagement>    
+                 
+<!-- add spring-cloud-starter-tencent-polaris-discovery dependency  -->
+<dependencies>
+    <dependency>
+        <groupId>com.tencent.cloud</groupId>
+        <artifactId>spring-cloud-starter-tencent-polaris-discovery</artifactId>
+    </dependency>
+</dependencies>
 
-Based on Spring Cloud Tencent, you only need a small configuration to launch Spring Cloud and micro-service's joint solutions.
-
-## Key Features
-
-* **Service Registration and Discovery**: Based on Spring Cloud's discovery and registration standard.
-* **Service Routing and LoadBalancer**: Based on ribbon's API port, provide dynamic routing and load balancing use cases.
-* **CircuitBreaker Node**: Support circuitbreaker auto-reset ability, ensure the reliability of distributed server
-* **Rate Limiter**: Support rate limit of microservice and gateway, ensure the stability of backend, one can configure policies and traffic data from the control panel
-* **Metadata Delivery**: Support metadata delivery between gateways and microservices.
-
-## Components
-
-**[Polaris](https://github.com/PolarisMesh/polaris)**：Polaris Spring Cloud operation centre, provide solutions to registration, dynamic routing, load balancing and circuitbreaker.
-
-## How to build
-
-* master's branch matches Spring Cloud Hoxton, support lowest at JDK 1.8.
-
-Spring Cloud Tencent uses Maven to construct, the fastest way is to clone project to local files, then execute the following orders:
-
-```bash
-./mvnw install
-```
-
-When all the steps are finished, the project will be installed in local Maven repository.
-
-## How to Use
-
-### How to Introduce Dependency
-
-Add the following configurations in dependencyManagement, then add the dependencies you need.
-At the same time, you need to pay attention to the Spring Cloud version corresponding to Spring Cloud Tencent, and then the corresponding Spring Boot version.
-For example, Spring Cloud Tencent's 1.0.1.Hoxton.SR9 corresponds to the Spring Cloud Hoxton version and requires Spring Boot 2.3.x.
