 as they tell you what this is all about, explain how to install the
 kernel, and what to do if something goes wrong.
 
+What is GNU Linux-libre?
+------------------------
+
+  GNU Linux-libre is a Free version of the kernel Linux (see below),
+  suitable for use with the GNU Operating System in 100% Free
+  GNU/Linux-libre System Distributions.
+  http://www.gnu.org/distros/
+
+  It removes non-Free components from Linux, that are disguised as
+  source code or distributed in separate files.  It also disables
+  run-time requests for non-Free components, shipped separately or as
+  part of Linux, and documentation pointing to them, so as to avoid
+  (Free-)baiting users into the trap of non-Free Software.
+  http://www.fsfla.org/anuncio/2010-11-Linux-2.6.36-libre-debait
+
+  Linux-libre started within the gNewSense GNU/Linux distribution.
+  It was later adopted by Jeff Moe, who coined its name, and in 2008
+  it became a project maintained by FSF Latin America.  In 2012, it
+  became part of the GNU Project.
+
+  The GNU Linux-libre project takes a minimal-changes approach to
+  cleaning up Linux, making no effort to substitute components that
+  need to be removed with functionally equivalent Free ones.
