Start step
The Start step represents the beginning of your flow on the flow canvas.
The Start step does not get rendered to an end user when a flow is run or published. It is only used as a starting point to connect to when you begin adding steps to the flow canvas.
Overview

-
When you create a flow and open the flow canvas, the Start step is already placed on the canvas.
-
Flows can only have one Start step, which cannot be deleted or duplicated.
-
Only one step can be connected to the Start step, using an outcome (typically named "Go"). Subsequent steps can however be connected to multiple outcomes. See Outcomes.
-
If you are using navigation with multiple unconnected steps to deliver a non-sequential flow, your first step must still connect to the Start step.
