# Example: An 'Approval' gate
<a name="workflows-approval-example"></a>

The following example shows how to add an **Approval** gate called `Approval_01` between two actions called `Staging`, and `Production`. The `Staging` action runs first, the `Approval_01` gate second, and the `Production` action last. The `Production` action only runs if the `Approval_01` gate is unlocked. The `DependsOn` property ensures that the `Staging`, `Approval_01`, and `Production` phases run in sequential order.

For more information about the **Approval** gate, see [Requiring approvals on workflow runs](workflows-approval.md).
