 ## How to use the sample (SampleViewer)
 
-1. The SampleViewer Scene should open by default, if it is not open, click the **SampleViewer** scene to open it.
+1. The SampleViewer Level should open by default, if it is not open, click the **SampleViewer** Level to open it.
 2. Click play.
 3. Using the UI, enter an APIKey in the input field to the top left. 
-4. Open the **Samples** drop down, and click **HitTest** to open the level.
+4. Open the **Samples** drop down, and click **HitTest** to open the Level.
 5. Click a building. The building's ID's will show up on a 3D UI Component.

-1. Open the **HitTest** level.
+1. Open the **HitTest** Level.
 2. Click on the **ArcGISMap** Actor and set your API key in the **Details** panel. 
 3. Click play.
 4. Click a building. The building's ID's will show up on a 3D UI Component.
 
 ## How it works
 
 1. Create an ArcGIS Map.
-2. Add an **ArcGISPawn** to the scene.
-3. Within the Level Blueprint, create an Input mapping. Off the **Pressed** node, drag off and create a **Line Trace by Channel**.
-4. Drag off the Exec node, and create an **ArcGISRaycast Hit**.
-5. Break the **ArcGISRaycast Hit Result** and drag off the **FeatureID** node.
-6. Convert this integer to a string, and connect it to a print node.
-7. Enter your **APIKey** in the **APIMapCreator**.
-8. Hit play. Once the scene is running click a building. The building's ID's will show up in a debug on screen. 
+2. Add an **ArcGISPawn** to the Level.
+3. Within the HitTest folder, drag the ArcGISRaycast Blueprint into the Level.
+4. In the UI folder within the HitTest folder, drag the bp_featureId Actor into the Level.
+5. Add a Sphere Static Mesh Actor into the Level and call it 'HitLocation'.
+6. In the Outliner panel, select the ArcGISRaycast Actor.
+7. Navigate to the Default sections in the Details Panel. For each variable shown in the image, click on the drop-down and add the respective Actor as its reference.

+8. Select the **ArcGISMap** Actor in the Outliner panel, and enter your **APIKey** in the Authentication section in the Details panel.
+9. Hit Play. Once the Level is running, hold Shift and click a building. The building's ID will show up in a debug on screen.
