We are always very happy to have contributions, whether for trivial cleanups or big new features.
We want to have high quality, well documented codes for each programming language, as well as the surrounding [ecosystem](https://github.com/apache/incubator-rocketmq-externals) of integration tools that people use with RocketMQ.
We want to have high quality, well documented codes for each programming language, as well as the surrounding [ecosystem](https://github.com/apache/rocketmq-externals) of integration tools that people use with RocketMQ.
Nor is code the only way to contribute to the project. We strongly value documentation, integration with other project, and gladly accept improvements for these aspects.
Apache RocketMQ is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
Follow this checklist to help us incorporate your contribution quickly and easily:
-[x] Make sure there is a [JIRA issue](https://issues.apache.org/jira/projects/ROCKETMQ/issues/) filed for the change (usually before you start working on it). Trivial changes like typos do not require a JIRA 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 `[ROCKETMQ-XXX] Fix UnknownException when host config not exist`. 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 integration-test in [test module](https://github.com/apache/rocketmq/tree/master/test).
- [ ] Run `mvn -B clean apache-rat:check findbugs:findbugs checkstyle:checkstyle` to make sure basic checks pass. Run `mvn clean install -DskipITs` to make sure unit-test pass. Run `mvn clean test-compile failsafe:integration-test` to make sure integration-test pass.
-[ ] If this contribution is large, please file an [Apache Individual Contributor License Agreement](http://www.apache.org/licenses/#clas).
