# Set up merge queue integration

> To allow users to merge stacks via the Graphite UI, Graphite needs to know who to hand off PRs to for merging

| Merge mechanism | Integration |
| - | - |
| No merge queue | You can skip this step. Users will be able to merge stacks directly through the Graphite UI without any additional setup. |
| Non-Graphite merge queue | You need to set up the merge queue integration for each repo so that users can enqueue stacks from the Graphite UI. For instructions, refer to [External Merge Queue Integration (Beta)](/docs/external-merge-queue-integration). |
| Graphite merge queue | To learn about Graphite's stack-optimized merge queue, refer to [Merge queue](/docs/graphite-merge-queue). |
