That is the link to the v6 community edition Kickstart app, which is an open source BPM suite with tools in the UI for designing and deploying processes. You can find more on that at http://www.baeldung.com/activiti-kickstart-and-rest-apps . Or if you just want to embed the Activiti process engine in your app and have it execute predefined processes then you might instead want to look at Getting started with Activiti and Spring Boot
