 **Project Requirements**
-* Any Project built which uses Atom as its rendering Agent. AutomatedTesting is good.
+* Automated Testing project is used with the MeshBase.prefab in this workflow. If you ignore the prefab any project can be used for exploratory testing.
 * Editor applications launched with default or desired RHI options.
 * GPU with recent driver updates.
 * Windows PC default RHI is DX12 (create a shortcut with additional parameter `-rhi=vulkan` or use other setreg methods for specifying Vulkan on Windows).
