 * **:green_circle: Action**: In the _**Package Manager**_ window, from the list of _**Samples**_ for the Perception package, click on the _**Import into Project**_ button for the sample named _**Tutorial Files**_.
 
-Once the sample files are imported, they will be placed inside the `Assets/Samples/Perception` folder in your Unity project. You can view your project's folder structure and access your files from the _**Project**_ tab of the editor, as seen in the image below:

 As seen above, the new Scene already contains a camera (`Main Camera`) and a light (`Directional Light`). We will now modify the camera's field of view and position to prepare it for the tutorial. 
 
-* **:green_circle: Action**: Click on `Main Camera` and in the _**Inspector**_ tab, modify the camera's `Position`, `Rotation`, `Projection` and `Size` to match the screenshot below. (Note that `Size` only becomes available once you set `Projection` to `Orthographic`)
+* **:green_circle: Action**: Click on `Main Camera` and in the _**Inspector**_ tab, make sure the camera's `Position`, `Rotation`, `Projection` and `Field of View` match the screenshot below.

 For this tutorial, we prefer our light to not cast any shadows, therefore:

-In this view, you will also see the real-time visualizations we discussed before shown on top of the camera's view. In the top right corner of the window, you can see a visualization control panel, through which you can enable or disable visualizations for individual labelers. That said, we currently have no foreground objects in the Scene yet, so no bounding boxes or semantic segmentations will be displayed.

 Note that disabling visualizations for a labeler does not affect your generated data. The annotations from all labelers that are active before running the simulation will continue to be recorded and will appear in the output data.

-Here, you can also specify a name for the run, the number of Iterations the Scenario will execute for, and the number of _**Instances**_ (number of nodes the work will be distributed across) for the run. 
+Here, you can also specify a name for the run, the number of Iterations the Scenario will execute for, and the number of _**Instances**_ (number of nodes the work will be distributed across) for the run.

+> :information_source: You can ignore the ***Optional Configuration*** section for now. This is useful if you plan to specify a configuration for your Scenario (including the Randomizers) that will override the values set in the Scenario UI, in Unity Simulation. To generate a configuration, you can click on the ***Generate JSON Config*** button provided in the ***Inspector*** view of Scenario components.
