-We want to have high quality, well documented codes for each programming language. These, as well as the surrounding [ecosystem](https://github.com/rocketmq) of integration tools that people use with RocketMQ, are critical aspects of the project.

 ## 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 wiki 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).
