+We suggest implementing the parts of this project in the following
+order to make your job easier:
+
+@enumerate
+@item
+Buffer cache (@pxref{Buffer Cache}).  Implement the buffer cache and
+integrate it into the existing file system.  At this point all the
+tests from project 2 (and project 3, if you're building on it) should
+still pass.
+
+@item
+Extensible files (@pxref{Indexed and Extensible Files}).  After this
+step, your project should pass the file growth tests.
+
+@item
+Subdirectories (@pxref{Subdirectories}).  Afterward, your project
+should pass the directory tests.
+
+@item
+Remaining miscellaneous items.
+@end enumerate
+
+You should think about synchronization throughout.
