 This repository contains a number of projects to illustrate various usages of 
Dubbo-Spi-Extensions from basic to advanced, pls. check README in each 
individual sub projects. It is also helpful to cross reference to [Dubbo User 
Manual](https://dubbo.apache.org/zh-cn/overview/tasks/) to understand the 
features demoed in this project.
 
-What's more, [dubbo-go](https://github.com/apache/dubbo-go) samples are moved 
to [dubbo-go-samples](https://github.com/apache/dubbo-go-samples).
+What's more, 
[dubbo-spi-extensions](https://github.com/apache/dubbo-spi-extensions) .
