-# Tutorial – Import and play back Alembic
-
-This quick tutorial covers adding Alembic assets to your Project and using them in Unity. It demonstrates importing and playing back Alembic content.
-
-1. Drag an Alembic (.abc) file into the Project view. This imports the Alembic Asset into Unity.
-
-   ![Drag the file](images/drag-to-project.png)
-
-2. Drag the Alembic Asset into the Scene.
-
-3. Open the **Alembic Stream Player** component in the Inspector and scrub the **Time** property.
-
-   If you are unfamiliar with the term *scrub*, it basically means to move the control left and right. In Unity, you can click-and-drag over the label on a control to move it left and right.
-
-   ![Scrub the time](images/scrub-time.png)
-
-   Next, you can learn how to play back the Alembic animation using the [Timeline Editor](https://docs.unity3d.com/Manual/TimelineEditorWindow.html).
-
-4. Select your Alembic object in the Scene view and open the Timeline Editor (top menu: **Window** > **Sequencing** > **Timeline**).
-
-5. Click the **Create** button to [create a Director component and a Timeline Asset](https://docs.unity3d.com/Manual/TimelineWorkflowCreatingAssetInstance.html) and save it to file.
-
-   Unity displays the Timeline Editor with a default Animation Track.
-
-   ![Timeline](images/timeline.png)
-
-6. Remove the Animation Track (select **Delete** from the context menu or the Track menu).
-
-7. Drag the Alembic object from the Scene onto the Timeline Editor and select **Add Clip With Alembic Track** from the pop-up menu.![Timeline](images/timeline2.png)
-
-   This creates an Alembic Track with an Alembic clip.
-
-8. Now you can [scrub the Timeline Playhead or use the Timeline Playback Controls](https://docs.unity3d.com/Manual/TimelinePlaybackControls.html) to see the animation playing in Unity.
