@@ -7,6 +7,7 @@ This page covers the process of how to use the RenderGraph API to write a render
 To begin, your render pipeline needs to maintain at least one instance of [RenderGraph](../api/UnityEngine.Rendering.RenderGraphModule.RenderGraph.html). This is the main entry point for the API. You can use more than one instance of a render graph, but be aware that Unity does not share resources across `RenderGraph` instances so for optimal memory usage, only use one instance.
