You can use the Annotation shape to add notes and comments to your flow. By documenting the functionality of a flow, you can share information with other developers.
At run time, annotations do not have any affect on flow processing.
In the Explorer panel, click Cases, and then click the case type that you want to open.
On the Workflow tab, click Life cycle.
Hover over a process in a stage, and then click the Configure process icon.
Click the Flow shapes icon, and then click Annotation.
Double-click the Annotation shape.
Replace the default text with your notes or comments.
Resize the Annotation shape to fit the text.
Drag the Annotation shape to a different position on the canvas, based on the functionality that you are documenting.
Click Save.
