-Examples of dubbo-go
-
-## What does this contain
-
-* helloworld
-
-    A simplest example. It contain 'go-client', 'go-server', 'java-server' of dubbo protocol. 
-
-* general
-
-    A general example. It had validated zookeeper registry and different parameter lists of service. 
-  And it has a comprehensive testing with dubbo/jsonrpc protocol. You can refer to it to create your first complete dubbo-go project.
-
-* generic
-
-    A generic reference example. It show how to use generic reference of dubbo-go.
-
-* configcenter
-
-    Some examples of different config center. There is only one -- zookeeper at present.
-
-## How to build and run
-
-> Take `helloworld` as an example
-
-java server
-
-```bash
-cd helloworld/dubbo/java-server
-sh build.sh
-
-cd ./target
-tar -zxvf user-info-server-0.2.0-assembly.tar.gz
-cd ./user-info-server-0.2.0
-sh ./bin/server.sh start
-```
-
-java client
-
-```bash
-cd helloworld/dubbo/java-client
-sh build.sh
-
-cd ./target
-tar -zxvf user-info-client-0.2.0-assembly.tar.gz
-cd ./user-info-client-0.2.0
-sh ./bin/server.sh start
-```
-
-go server
-
-* $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]
-
-```bash
-cd helloworld/dubbo/go-server
-sh ./assembly/$ARCH/$ENV.sh
-
-cd ./target/linux/user_info_server-0.3.1-20190517-0930-release
-# $SUFFIX is a suffix of config file,
-# such as server_zookeeper.yml when $SUFFIX is "zookeeper", 
-# if $SUFFIX = "", default server.yml
-sh ./bin/load.sh start $SUFFIX
-```
-
-go client
-
-* $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]
-
-```bash
-cd helloworld/dubbo/go-client
-sh ./assembly/$ARCH/$ENV.sh
-
-cd ./target/linux/user_info_client-0.3.1-20190517-0921-release
-# $SUFFIX is a suffix of config file,
-# such as client_zookeeper.yml when $SUFFIX = zookeeper", 
-# if $SUFFIX = "", config file is client.yml
-sh ./bin/load_user_info_client.sh start $SUFFIX
-```
