 Two of the Unity Robotics repos (URDF Importer and TCP Connector) have been forked from the Siemens ROS# repo.
 
-In the URDF Importer we have added the functionality to instantiate a robot from URDF into a Unity scene with [Articulation Body](https://docs.unity3d.com/2020.1/Documentation/ScriptReference/ArticulationBody.html) components on their corresponding joints. 
+In the URDF Importer we have added the functionality to instantiate a robot from URDF into a Unity scene with [Articulation Body](https://docs.unity3d.com/2020.2/Documentation/Manual/class-ArticulationBody.html) components on their corresponding joints. 
 
 Aside from facilitating communication with the TCP Endpoint, the TCP Connector contains the `MessageGeneration` code from ROS#. We added the extra functionality that when generating a C# class from a ROS message, functions are also generated that will serialize and deserialize the messages as ROS would internally.
 
 
 I don't see an option to Import Robot from URDF, or I have compile errors upon importing the URDF-Importer.

-The [ArticulationBody](https://docs.unity3d.com/2020.2/Documentation/ScriptReference/ArticulationBody.html) has dependencies on Unity Editor versions [2020.2.0](https://unity3d.com/unity/whats-new/2020.2.0)+. Try updating your project to the latest 2020.2 release.

 1. Click the newly added project to open it.
 
-1. Unity should open the project to a scene titled `EmptyScene`.  If it did not, you can find it in the Project window in the Assets/Scenes directory, and double-click to open it now.
+1. In Unity, double click to open the `Assets/Scenes/EmptyScene` scene if it is not already open.
     > Note: If you have some experience with Unity and would like to skip the scene setup portion, you can open the scene named `TutorialScene` now and skip ahead to [Setting up the robot](#setting-up-the-robot).
 
     > Note: Only one Unity scene should be open at a time. If you see multiple scenes open in the Hierarchy view, double-click the desired scene, e.g. `Assets/Scenes/EmptyScene`, to open it and close the other scenes.
