I got a copy of alfresco community(alfresco-content-services-community-full-distribution-6.0.7-ga.zip) from here and set it up in a running tomcat installation. However, when it comes to setting up a custom workflow, the only info I had was from this source. I tried this but was not able to setup a custom workflow to use. Would there be a guide I'm missing that would help me in setting up a custom workflow? If a modern version of alfresco can help, I'd be happy to look into it.
