# Merge Node

> Learn how to use the merge node in a workflow to wait until multiple branches are complete, including configuration steps and a usage example. It suits scenarios that require multi-step approvals, such as an initial and a secondary review, before moving to the next step.

When a workflow contains multiple branches and you want the process to continue only after all branches complete, use a merge node. The workflow proceeds only after every node on all incoming lines of the merge node has finished, creating a wait effect.

**Example**: During review, the process moves to the final review only after both the initial review and the secondary review are complete.

## Configure a Merge Node

1. Go to the Premium workflow design page and drag a merge node onto the canvas.
2. Click the merge node, and then connect the branches you want to merge into it.

<Note>
  Nodes after the merge node are activated only after all branches before the merge node complete.
</Note>

## Usage Example

See the workflow diagram below:

* The workflow starts and the initial review node is activated.
* Once the initial review is complete, both the Secondary Review 1 and Secondary Review 2 approval nodes are activated, and the automated tasks are triggered.
* Once both Secondary Review 1 and Secondary Review 2 are complete, the final review node is activated.
* Once the final review is complete, the workflow ends.
