 * **Action**: Click on the _**+**_ sign at the top-left corner of the _**Package Manager**_ window and then choose the option _**Add package frim git URL...**_. 
 * **Action**: Enter the address `com.unity.perception` and click _**Add**_.
 
-**Note:** If you would like a specific version of the package, you can append the version to the end of the url. For example `com.unity.perception@0.1.0-preview.5`. For this tutorial, **we do not need to add a version**. You can also install the package from a local clone of the Perception repository. More inofrmation on installing local pacakges is available [here](https://docs.unity3d.com/Manual/upm-ui-local.html).

 It will take some time for the manager to download and import the package. Once the operation finishes, you will see the newly download Perception package automatically selected in the _**Package Manager**_, as depicted below:

 * **Action**: Choose `TutorialScene` (which is the Scene we have been working in) as your _**Main Scene**_ and the `SimulationScenario` object as your _**Scenario**_.
 
-Here, you can also specify a name for the run, the number of iterations the Scenario will execute for, and the number of concurrent _**Instances**_ 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. 
-* **Action**: Name your run `FirstRun`, set the number of iterations to `1000`, and instances to `1`. 
+* **Action**: Name your run `FirstRun`, set the number of iterations to `1000`, and instances to `20`. 
 * **Action**: Click _**Build and Run**_.
 
 Your project will now be built and then uploaded to USim. Depending on the upload speed of your internet connection, this might take anywhere from a few seconds to a couple of minutes.
