Welcome to the documentation and tutorials page of STEP-ONE!

The below tutorials walk you through how to create process-oriented scenarios with STEP-ONE. Because STEP-ONE is based on the ONE simulator and Flowable, it is advisable to also refer to their documentation:

• https://flowable.com/open-source/docs/
• http://akeranen.github.io/the-one/

Running & Configuring STEP-ONE simulations

• STEP-ONE scenarios can be run with Gradle, providing as argument the settings file to use:

./gradlew run --args samples/tutorial1_basic_messaging/settings.txt

• STEP-ONE processes can be created using the STEP-ONE version of Flowable BPMN modeller:
  • Install Docker and Docker Compose
  • Go to step-one-modeler directory, (containing docker-compose.yml file ). cd ./step-one/step-one-modeler
  • Run docker-compose up
  • After the web-app service has finished initialising, use a browser to open the modeller at: http://localhost:8888/flowable-modeler
