I think this is too much up front. This expects the user to know about "run tree" information. I think probably better to just say like "This tutorials shows how to correctly trace a PromptFlow application in LangSmith. It covers initial setup, nested tracing, and calling the promptflow tools from a langgraph application" or something like that

I think we prefer regular sentence casing "## Creating nested traces"
