A Flow Link step hands a run off to a different flow, rather than continuing within the current one. This could be another section of your current flow or another flow entirely.

Adding a Flow Link step

1. Add a Flow Link step to your flow.
2. Choose the flow it should hand off to and the message it should trigger.

Use a Flow to signal another flow to start or when a single flow has grown complex enough that splitting part of it out (and linking to it) keeps things easier to maintain (like a main menu).
