-The advanced scheduler builds on the priority scheduler. You should
-have the priority scheduler working, except possibly for priority
-donation, before you start work on the advanced scheduler.
+Like the priority scheduler, the advanced scheduler chooses the thread
+to run based on priorities. However, the advanced scheduler does not do
+priority donation. Thus, we recommend that you have the priority
+scheduler working, except possibly for priority donation, before you
+start work on the advanced scheduler.
