+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier

+Examples of dubbo-go
+
+## What does this contain
+
+* helloworld
+
+    A simplest example. It contain 'go-client', 'go-server', 'java-server' of dubbo protocol. 
+    
+* direct
+
+    A direct example. This feature make start of dubbo-go get easy. 
+    
+* async
+
+    An async example. dubbo-go supports client to call server asynchronously. 
+
+* general
+
+    A general example. It had validated zookeeper registry and different parameter lists of service. 
+  And it has a comprehensive testing with dubbo/jsonrpc/grpc/rest protocol. You can refer to it to create your first complete dubbo-go project.
+
+* generic
+
+    A generic example. It show how to use generic feature of dubbo-go.
+
+* configcenter
+
+    Some examples of different config center. There are three -- zookeeper, apollo and nacos at present.
+
+* multi_registry
+
+    An example of multiple registries.
+
+* registry
+
+    Some examples of different registry. There are kubernetes, nacos and etcd at present.
+
+	**Note**:
+
+	When use different registry, you need update config file, but also must import the registry package. see the etcd `README`
+
+* filter
+
+    Some examples of different filter. Including custom_filter and tpslimit
+    
+* router
+
+    Some router examples. Now, a condition router example is existing. 
+
+* seata
+
+    Transaction system examples by seata.
+
+* shop    
+
+    Shop sample, make consumer and provider run in a go program.
+        
+* tracing
+
+    Some tracing examples. We have tracing support of dubbo/grpc/jsonrpc protocol 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/$ENV.sh
+cd ./target/$ARCH/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/$ENV.sh
+cd ./target/$ARCH/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
+```
+
+docker env
+
+```bash
+docker run -d --name zk zookeeper
+docker run -d --network container:zk registry.cn-hangzhou.aliyuncs.com/scottwang/go-server
+docker run -d --network container:zk registry.cn-hangzhou.aliyuncs.com/scottwang/go-client
+```
+
+## How to debug with Goland
+
+### Edit Configurations
+
+![](.images/edit_configuratios.png)
+
+### Configure `Environment Variable`
+
+1. Add `APP_LOG_CONF_FILE`. eg: `/home/xx/dubbogo-samples/helloworld/client/conf/log.yml`
+2. Add `CONF_CONSUMER_FILE_PATH` eg: `/home/xx/dubbogo-samples/helloworld/client/conf/client.yml`
+3. Add `CONF_PROVIDER_FILE_PATH` eg: `/home/xx/dubbogo-samples/helloworld/server/conf/server.yml`
+
+![](.images/edit_env.png)
+	
+### Apply & Run
+
+## How to contribute
+
+If you want to add some samples, we hope that you can do this:
+1. Adding samples in appropriate directory. If you dont' know which directory you should put your samples into, you can get some advices from dubbo-go community.
+2. You must run the samples locally and there must be no any error.
+3. If your samples have some third party dependency, including another framework, we hope that you can provide some docs, script is better.
+4. Please make pr to https://github.com/dubbogo/dubbo-samples instead of https://github.com/apache/dubbo-samples. We will synchronize to apache/dubbo-samples regularly.

+### Use Async Feature
+
+Implement this interface
+
+```golang
+//AsyncCallbackService callback interface for async
+type AsyncCallbackService interface {
+	CallBack(response CallbackResponse) // callback
+}
+```
+
+like this
+
+```golang
+type UserProvider struct {
+	GetUser func(ctx context.Context, req []interface{}, rsp *User) error
+}
+
+func (u *UserProvider) CallBack(res common.CallbackResponse) {
+	fmt.Println("CallBack res:",res)
+}
+```
+
+Dubbogo will run Async logic once network request finished.

+### 1.Run apollo as config center
+
+* download this folder as below
+
+[docker-quick-start](https://github.com/ctripcorp/apollo/tree/master/scripts/docker-quick-start)
+
+* enter docker-quick-start folder and run
+
+```docker-compose up```
+
+### 2.Run java server & java client following [README](https://github.com/dubbogo/dubbo-samples/blob/master/golang/README.md)
+
+* Set config item **app.id**  in /resources/META-INF/app.properties like
+
+```
+app.id=application
+```
+
+* Set apollo meta url in  /resources/META-INF/spring/dubbo.provider.xml and /resources/META-INF/spring/dubbo.consumer.xml like
+
+```
+<dubbo:config-center protocol="apollo" address="1.1.1.1:8080"/>
+```
+
+Build and run it , enjoy.
+ 
+### 3.Run java server & go client 
+
+Stop java client. Copy go client configuration file [dubbo.properties](https://github.com/dubbogo/dubbo-samples/golang/blob/master/configcenter/apollo/dubbo/go-client/profiles/dev/dubbo/config/user-info-client/dubbo.properties) as 
+namespace dubbo.properties in apollo.
+
+Then start go client following [README](https://github.com/dubbogo/dubbo-samples/blob/master/golang/README.md).
+
+### 4.Run go server
+
+The same as step 3. Copy go server configuration file [dubbo.properties](https://github.com/dubbogo/dubbo-samples/blob/master/golang/configcenter/apollo/dubbo/go-server/profiles/dev/dubbo/config/user-info-server/dubbo.properties) as 
+namespace dubbo.properties in apollo.

+### 1.Run zookeeper as config center
+
+```docker-compose -f docker/docker-compose.yaml up -d```
+
+### 2.Run java server & java client following [README](https://github.com/dubbogo/dubbo-samples/blob/master/golang/README.md)(You must run java program to initialize configuration in zookeeper)
+
+Java program will create consumer & provider common configuration in /dubbo/config/dubbo/dubbo.properties, consumer configuration in /dubbo/config/user-info-client/dubbo.properties
+ and provider configuration in /dubbo/config/user-info-server/dubbo.properties.
+ 
+### 3.Run java server & go client 
+
+Stop java client. Copy go client configuration file [dubbo.properties](https://github.com/dubbogo/dubbo-samples/blob/master/golang/configcenter/zookeeper/dubbo/go-client/profiles/dev/dubbo/config/user-info-client/dubbo.properties) as 
+zookeeper file /dubbo/config/user-info-client/dubbo.properties in zookeeper node path /dubbo/config/user-info-client/.
+
+Use the script to set configuration file to zookeeper as below
+```
+./zkCli.sh -server 127.0.0.1:2181 set /dubbo/config/user-info-client/dubbo.properties "dubbo.service.com.ikurento.user.UserProvider.cluster=failback
+dubbo.service.com.ikurento.user.UserProvider.protocol=myDubbo
+dubbo.protocols.myDubbo.port=20000
+dubbo.protocols.myDubbo.name=dubbo
+"
+```
+
+Then start go client following [README](https://github.com/dubbogo/dubbo-samples/blob/master/golang/README.md).
+
+### 4.Run go server
+
+The same as step 3. Copy go server configuration file [dubbo.properties](https://github.com/dubbogo/dubbo-samples/blob/master/golang/configcenter/zookeeper/dubbo/go-server/profiles/dev/dubbo/config/user-info-server/dubbo.properties) as 
+zookeeper file /dubbo/config/user-info-server/dubbo.properties in zookeeper node path /dubbo/config/user-info-server/.
+
+Use the script to set configuration file to zookeeper as below
+```
+./zkCli.sh -server 127.0.0.1:2181 set /dubbo/config/user-info-server/dubbo.properties "dubbo.service.com.ikurento.user.UserProvider.cluster=failback
