There is a section after using the wizard about  installing the eclipse designer plugin .

1.5. Reporting a problem

Every self-respecting developer should read  How to Ask Wisely .

Once you've read it, you can   submit issues and comments on the user forum , and create issues on our JIRA issue tracker .

Although Activiti is hosted on GitHub, do not use GitHub's issue system to report issues. If you want to report an issue, don't create a GitHub issue, but use our JIRA .

1.6. Experimental Features

Sections marked  [EXPERIMENTAL]  , don't think how stable the features mentioned are.

所有impl包中的类，都是一些内部实现，不会很稳定。不过，向导中作为配置值的那些类，都是受支持且十分稳定的。

1.7. Internal implementation classes

 In the jar file, the inclusions .impl.的包 (eg  org.activiti.engine.impl.db) are all implementation classes, and they are all inner classes. There is no guarantee that a class or interface within an implementing class is stable.
