# Set task blockers

Task blockers let you define dependencies between tasks in a project so your team always knows what needs to happen first. You can mark a task as waiting on another, or flag that it is holding something else up.

### Set a blocker from the Task modal

1. Go to **Projects** in the left panel.
2. Open the **workspace** where your project lives, then click the project to open it.
3. Click the task you want to assign a blocker to.
4. In the Task modal, find the **Blockers** section.
5. Select the blocker type.
6. **Blocked By** — The task you are editing is waiting on another task to be completed before it can move forward. Use this when your task cannot start until something else is done.
7. **Blocking** — The task you are editing is holding another task back. Use this when your task must be completed before work on another task can begin.
8. Choose the task from the list.

**Expected outcome:** Your task is now linked to the selected task. Both tasks will reflect the dependency, and changes are saved automatically.

**FAQ**

**Can a task be blocked by more than one task at the same time?** Yes, it is possible to select multiple tasks to block a specific task.

**Can a task block more than one task at the same time?** Yes, it is possible to select a single task that blocks multiple tasks at once.

**What happens if I complete a task that is blocking another task?** When you complete a task that is blocking another task, the blocked task automatically becomes ready to proceed.
