[jbpm-users] Where to begin learning JBPM-6

Hi, I am new to jbpm. I downloaded jbpm 6 installer from sourceforge and did ant install.demo, ant start.demo and played with 10 minute tutorials on both workbench and Eclipse. After that I did ant.stop.demo and ant clean.demo. I tried to read user guide, but it is not clear to me how I start building my own workflows. Are there any videos or tutorials on how one can start jbpm for their own workflows? If someone could give me a link where I can start working on an example problem (not the demo) in the jbpm-installer directory that would be nice. Thanks. Prakashan
