Interface Node
=================

Overview
-----------

Managing different flowcharts can be difficult especially when the flowcharts is large and complex.
**Interface node** allows you to encapsulate flowchart outputs as one node.

Procedure to Use
------------------

1. Right click the node where you want to insert and insert an Interface node.
