+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at dev@dubbo.apache.org. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

+
+## Contributing to dubbo
+Dubbo is released under the non-restrictive Apache 2.0 license, and follows a very standard Github development process, using Github tracker for issues and merging pull requests into master. If you want to contribute even something trivial please do not hesitate, but follow the guidelines below.
+
+### Sign the Contributor License Agreement
+Before we accept a non-trivial patch or pull request we will need you to sign the Contributor License Agreement. Signing the contributor’s agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. Active contributors might be asked to join the core team, and given the ability to merge pull requests.
+
+### Contact
+
+#### Mailing list
+
+The mailing list is the recommended way for discussing almost anything that related to Dubbo. Please refer to this [guide](https://github.com/apache/dubbo/wiki/Mailing-list-subscription-guide) for detailed documentation on how to subscribe.
+
+- [dev@dubbo.apache.org](mailto:dev-subscribe@dubbo.apache.org): the develop mailing list, you can ask question here if you have encountered any problem when using or developing Dubbo.
+- [commits@dubbo.apache.org](mailto:commits-subscribe@dubbo.apache.org): all the commits will be sent to this mailing list. You can subscribe to it if you are interested in Dubbo's development.
+- [notifications@dubbo.apache.org](mailto:notifications-subscribe@dubbo.apache.org): all the Github [issue](https://github.com/apache/dubbo/issues) updates and [pull request](https://github.com/apache/dubbo/pulls) updates will be sent to this mailing list.
+
+### Reporting issue
+
+Please follow the [template](https://github.com/apache/dubbo/issues/new?template=dubbo-issue-report-template.md) for reporting any issues.
+
+### Code Conventions
+Our code style is almost in line with the standard java conventions (Popular IDE's default setting satisfy this), with the following additional restricts:
+* If there are more than 120 characters in current line, start a new line.
+
+* Make sure all new .java files to have a simple Javadoc class comment with at least a @date tag identifying birth, and preferably at least a paragraph on what the class is for.
+
+* Add the ASF license header comment to all new .java files (copy from existing files in the project)
+
+* Make sure no @author tag added to the file you contribute since @author tag is not used at Apache, other ways such as cvs will record all your contributions fairly.
+
+* Add some Javadocs and, if you change the namespace, some XSD doc elements.
+
+* A few unit tests should be added for a new feature or an important bugfix.
+
+* If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project).
+
+* When writing a commit message please follow these conventions, if you are fixing an existing issue please add Fixes #XXX at the end of the commit message (where XXX is the issue number).
+
+### Contribution flow
+
+This is a rough outline of what a contributor's workflow looks like:
+
+* Fork the current repository
+* Create a topic branch from where to base the contribution. This is usually master.
+* Make commits of logical units.
+* Make sure commit messages are in the proper format (see below).
+* Push changes in a topic branch to your forked repository.
+* Follow the checklist in the [pull request template](https://github.com/apache/dubbo/blob/master/PULL_REQUEST_TEMPLATE.md)
+* Before you sending out the pull request, please sync your forked repository with remote repository, this will make your pull request simple and clear. See guide below:
+```
+git remote add upstream git@github.com:apache/dubbo.git
+git fetch upstream
+git rebase upstream/master
+git checkout -b your_awesome_patch
+... add some work
+git push origin your_awesome_patch
+```
+* Submit a pull request to apache/dubbo and wait for the reply.
+
+Thanks for contributing!
+
+### Code style
+
+We provide a template file [dubbo_codestyle_for_idea.xml](https://github.com/apache/dubbo/tree/master/codestyle/dubbo_codestyle_for_idea.xml) for IntelliJ idea, you can import it to you IDE.
+If you use Eclipse you can config manually by referencing the same file.
+
+**NOTICE**
+
+It is very important to set the dubbo_codestyle_for_idea.xml, otherwise you will fail to pass the Travis CI. Steps to set the code style are as below:
+
+1. Enter `Editor > Code Style`
+2. To manage a code style scheme, in the Code Style page, select the desired scheme from the drop-down list, and click .
+From the drop-down list, select `Import Scheme`, then select this option `IntelliJ IDEA code style XML` to import scheme
+3. In the Scheme field, type the name of the new scheme and press ⏎ to save the changes.

+ 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.

+## What is the purpose of the change
+
+XXXXX
+
+## Brief changelog
+
+XXXXX
+
+## Verifying this change
+
+XXXXX
+
+Follow this checklist to help us incorporate your contribution quickly and easily:
+
+- [x] Make sure there is a [GITHUB_issue](https://github.com/apache/dubbo/issues) field for the change (usually before you start working on it). Trivial changes like typos do not require a GITHUB issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
+- [ ] Format the pull request title like `[Dubbo-XXX] Fix UnknownException when host config not exist #XXX`. Each commit in the pull request should have a meaningful subject line and body.
+- [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
+- [ ] Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add sample in [dubbo samples](https://github.com/apache/dubbo-samples) project.
+- [ ] Run `mvn clean install -DskipTests=false` & `mvn clean test-compile failsafe:integration-test` to make sure unit-test and integration-test pass.
+- [ ] If this contribution is large, please follow the [Software Donation Guide](https://github.com/apache/dubbo/wiki/Software-donation-guide).

+
+
+## Reporting a Vulnerability
+
+The Apache Software Foundation takes a rigorous standpoint in annihilating the security issues in its software projects. Apache Dubbo is highly sensitive and forthcoming to issues pertaining to its features and functionality.
+
+If you have apprehensions regarding Dubbo's security or you discover vulnerability or potential threat, don’t hesitate to get in touch with the Apache Dubbo Security Team by dropping a mail at security@dubbo.apache.org. In the mail, specify the description of the issue or potential threat. You are also urged to recommend the way to reproduce and replicate the issue. The Dubbo community will get back to you after assessing and analysing the findings.
+
+PLEASE PAY ATTENTION to report the security issue on the security email before disclosing it on public domain.
+
+## VULNERABILITY HANDLING
+
+An overview of the vulnerability handling process is:
+
+* The reporter reports the vulnerability privately to Apache.
+* The appropriate project's security team works privately with the reporter to resolve the vulnerability.
+* A new release of the Apache product concerned is made that includes the fix.
+* The vulnerability is publicly announced.
+
+A more detailed description of the process can be found [here](https://www.apache.org/security/committers.html).

+ *
+ * <dubbo:config-center namespace="governance" group="dubbo" />, 'dubbo=governance' is for governance rules while
