-// 6 - FOCUSING EDGES
-//  Even though Coati doesn't allow to activate an edge, you can still focus on
-//  edges. This doesn't change the currently active symbol (which would cause 
-//  Coati to hide everything but the edge). Instead Coati just highlights the
-//  relation's location in the code and scrolls you there, so you don't lose 
-//  context.
-//  Try to activate an edge that comes from the "ConsumerOfTheLastMember" class.
-//  Which one you pick doesn't really matter for this tutorial.
+// 7 - THAT'S IT
+//  You completed the tutorial on the graph view. There is still more to learn
+//  but I guess you will figure it out on your own. One last thing: If you see
+//  an element with a hatched background please call us. It's a runaway!
+//  Just kidding. Those are elements that are used within your code, but have no
+//  definition anywhere in your source folder (like the "int" symbol on the
+//  right hand side of the graph). So if you click them, Coati will display
+//  all the relations for the element, but the code view won't show a
+//	definition. If you want to learn more about Coati, go back to the central
+//  hub. It is called in the function below but you can also try to get there
+//  using only the graph.
