+## How To Contribute
+
+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/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.
+
+## Contributing code
+
+To submit a change for inclusion, please do the following:
+
+#### If the change is non-trivial please include some unit tests that cover the new functionality.
+#### If you are introducing a completely new feature or API it is a good idea to start a [RIP](https://github.com/apache/rocketmq/wiki/RocketMQ-Improvement-Proposal) and get consensus on the basic design first.
+#### It is our job to follow up on patches in a timely fashion. Nag us if we aren't doing our job (sometimes we drop things).
+
+## Becoming a Committer
+
+We are always interested in adding new contributors. What we look for are series of contributions, good taste and ongoing interest in the project. If you are interested in becoming a committer, please let one of the existing committers know and they can help you walk through the process.
+
+Nowadays,we have several important contribution points:
+#### Wiki & JavaDoc
+#### RocketMQ SDK(C++\.Net\Php\Python\Go\Node.js)
+#### RocketMQ Connectors
+
+##### Prerequisite
+If you want to contribute the above listing points, you must abide our some prerequisites:
+
+###### Readability - API must have Javadoc,some very important methods also must have javadoc
