One of the major problems in jbpm5.1 is its lack of documentation. Or at least a central place to find it.

The first place you need to look at is the official documentation:

• User Guide: http://docs.jboss.org/jbpm/v5.1/userguide/
• API: http://docs.jboss.org/jbpm/v5.1/javadocs/

Kris Verlaenen's blog (jBPM5 lead):

• http://kverlaen.blogspot.com/

Salaboy's Blog (Community lead ????):

• http://salaboy.wordpress.com/
• He is also writing a book about jBPM5.x. Should be out in a couple of months (??)

I have a bunch of basic examples using JBPM5:

When you feel confortable enough, you can start playing with emergency-service application. It tries to be a blue-print implementation of jBPM5 and Drools:

Also go through the blog by bpmn2user.

I found it very useful.

you know.. the best documentation for an open source project is the source code. If you want to know more about those specific classes you can directly look at the code and help us to improve the current docs. By the way, if you take a look at the master repository you will see that new classes and interfaces were added this last week:
