BPM add-on is used for modeling and running business processes. Processes are described using BPMN 2.0 notation. The add-on uses Flowable as a business process engine and bpmn-js rendering toolkit for process modeling.
This manual mostly describes features added by the add-on, not features provided by underlying frameworks, so you should be familiar with the Flowable engine.
Follow the instructions in the Add-ons section to install the add-on into your application.
