Example flows

There are built-in example flows that you can load. To do that, press ctrl+i -> Examples, and then choose one of the examples.

Running a flow

Whenever you deploy your flows, all of the flows from the enabled diagrams will be executed. The diagram is executed step by step, and the current state of the diagram is displayed in the debug tab (hamburger icon -> view -> Debug messages).

To restart the execution, you can select Restart Flows next to the Deploy button.

To see the current tokens in each node, you can use the context data tab: .

Select the small checkbox next to the Node section in this tab. This will automatically refresh the data whenever you click on a node. Next, whenever you click on a node, you will see the current tokens in that node.

Adding Custom Nodes

By default, there are common nodes and nodes for the example flows: hot-cold, Tic-Tac-Toe, and PrestaShop. See the nodes-generator tutorial for a detailed guide on how to edit these nodes.
