+Driver implementer's API guide
+==============================
 
 The kernel offers a wide variety of interfaces to support the development
 of device drivers.  This document is an only somewhat organized collection
 of some of those interfaces — it will hopefully get better over time!  The
 available subsections can be seen below.

+This section contains documentation that should, at some point or other, be
+of interest to most developers working on device drivers.
