README.md

 2. Navigate to ___Edit > Project Settings > Graphics___ and add the Lightweight Render Pipeline Asset you created to the __Render Pipeline Settings__ field.
 
 Note: Always store your new Render Pipeline Asset outside of the Scriptable Render Pipeline folder. This ensures that your Lightweight settings are not lost when merging new changes from the SRP repo.

+## Sample Scenes in ScriptableRenderPipelineData
+
+If you want some sample scenes to use with SRP, you can find them at the [ScriptableRenderPipelineData GitHub repository](https://github.com/Unity-Technologies/ScriptableRenderPipelineData).
+
+Clone the repo into your project's Assets\ folder, likely alongside your ScriptableRenderPipeline clone folder.  You can use the same cloning process as described above for the main ScriptableRenderPipeline repo.
+
+Previous iterations of the ScriptableRenderPipeline repo owned this sample scene data, in case you noticed it before, and wondered where it went.
