> Depending on the method you used to create your Script Graph, you might already have two Event nodes in your graph: Start and Update. For more information on these nodes, see [Events node](vs-events-reference.md).
After you've added a node to a graph, you can add additional nodes and [connect nodes in a Script Graph](vs-creating-connections.md) to create logic for your application.
You can also add a [Sticky Note](vs-sticky-notes.md) to add comments to a graph.
