 Sentinel Dubbo Adapter provides service consumer filter and provider filter
-for [Dubbo](http://dubbo.io/) services. 
+for [Apache Dubbo](https://dubbo.apache.org/en-us/) services.
+
+**Note: This adapter only supports Apache Dubbo 2.7.x and above.** For legacy `com.alibaba:dubbo` 2.6.x,
+please use `sentinel-dubbo-adapter` module instead.
 
 To use Sentinel Dubbo Adapter, you can simply add the following dependency to your `pom.xml`:
 
 ```xml
 <dependency>
     <groupId>com.alibaba.csp</groupId>
-    <artifactId>sentinel-dubbo-adapter</artifactId>
+    <artifactId>sentinel-apache-dubbo-adapter</artifactId>
     <version>x.y.z</version>
 </dependency>
 ```
 
-> Note: currently this adapter is not compatible with Dubbo 2.7.x due to its package renaming.
-We are working to support the latest Dubbo version.
-
 The Sentinel filters are **enabled by default**. Once you add the dependency,
 the Dubbo services and methods will become protected resources in Sentinel,
 which can leverage Sentinel's flow control and guard ability when rules are configured.
