Use this to build up a set one item at a time — for example, stepping through a project's features in a loop and collecting every unique usage type you encounter along the way.
Set vs. List: a List (array) keeps items in order and can hold duplicates — you access items by position, like "the 3rd item." A Set has no order and no duplicates — adding an item that's already there does nothing, and there's no "position" to ask for. Sets are for asking "is this here?" and for comparing groups of things; Lists are for ordered, step-by-step sequences.

Add the Add to Set node.
Feed in an existing set (or an empty one from the Set node) and the item to add.
The output is the updated set — if the item was already in the set, nothing changes.
