+// Steps to run this sample:
+// 1. Create a console app and replace Program.cs with this source
+// 2. Build the app (for example with dotnet build). My exe is produced in 
+//    "E:\temp\EventSourceSample\bin\Debug\net5.0\EventSourceSample.exe"
+// 3. Download PerfView if you don't already have it: https://github.com/microsoft/perfview/blob/main/documentation/Downloading.md
+// 4. In an admin command prompt, run this PerfView command substituting the path to your executable:
+//    PerfView.exe -OnlyProviders:MyEventSource run E:\temp\EventSourceSample\bin\Debug\net5.0\EventSourceSample.exe
+// 5. After PerfView finishes collecting, open the Events view and confirm that 1 event of type MyEventSource/HelloWorld was collected in
+//    addition to the other events
