+Important Notes About Configuration
+-----------------------------------
+
+Since v0.4.0, NLSR no longer creates Faces for the neighbors that are
+specified in ``nlsr.conf``. Instead, it relies on the pre-existence of
+the Faces in NFD. NLSR will obtain this information from NFD, and
+configure its neighbors using this information.
+
+For people who were relying on NLSR to automagically configure their
+networks, this must now be done with ``nfdc``. Its documentation can
+be found `here
+<https://named-data.net/doc/NFD/current/manpages/nfdc.html>`_
