Connect nodes and one node's output flows into the next node's input; that's how you build a workflow. This chapter covers connection rules, and how to tidy up, group and run a whole group.

## Connection rules

- Connect: drag from one node's output handle to another node's input handle;
- Single-connection inputs: an input that takes only one connection replaces the old connection when you add a new one (to swap a reference image, just drag in a new connection; there's no need to disconnect first). Inputs such as image references take several connections at once, and how many video inputs you can connect depends on the model;
- Disconnect: right-click a node and choose “Disconnect all”, or use the button of the same name on the toolbar when the node has two or more connections, to remove all of the node's connections at once.

## Tidy up and group

- Tidy the canvas: ⇧⌥F (Shift+Alt+F on Windows) rearranges the nodes automatically so the connections are neater. You can also right-click a node and choose “Tidy layout”, or click the tidy button on the canvas toolbar;
- Group: box-select several nodes and press ⌘/Ctrl + G. A toolbar appears above the group frame: run the whole group, duplicate the group, save as workflow, convert to storyboard group (when every node in the group is an image), ungroup, and batch download;
- Ungroup: ⌘/Ctrl + Shift + G. Batch download gets every result in the group at once.

## Running a group and storyboard groups

- Run the whole group: a “Run group” confirmation opens first with the credit estimate; once you confirm, every node in the group that can generate runs in the order of its connections;
- Run a whole chain: right-click a node and choose “Run chain” to run the chain from that node all the way down; you confirm the price first here too;
- Convert to storyboard group: available only when every node in the group is an image node (⌘/Ctrl + Alt + G). After converting, the toolbar changes to aspect ratio, grid count, an index switch and resolution, plus “Stitch” (combines the group's images into one large image), convert to normal group, duplicate, clear (deletes every image and connection in the group) and ungroup.

## Save as a reusable workflow

Select some nodes (they don't need to be grouped first), click “Save as workflow” on the multi-select toolbar, the node's right-click menu or the group toolbar, and give it a name. That segment is saved as a reusable workflow (only the node structure and settings are saved, not the generated results). You'll then find it under “My workflows” in the left toolbar: drag it onto the canvas to place it where you let go, or click “Send to canvas” to place it in the middle of the view. You can also right-click empty canvas and choose “Place workflow” to put it where you clicked. A placed workflow is grouped automatically, with the workflow's name as the group name. The group and the workflow are independent: ungrouping or changing the placed nodes doesn't change the saved workflow. In “My workflows” you can also rename and delete workflows; you're asked to confirm before a deletion. “Templates” holds the official templates that come with the product.
