-You can add the following line into \"${ccnxdir}/ccndrc\" in order to automatically
-start ccnx repo for the /ndn/keys prefix:
-
-    CCNR_GLOBAL_PREFIX=/ndn/keys
-
-For more information and documentation, refer to man pages and http://www.ccnx.org website.
-
-If you have your public key signed by NDN testbed operators and you installed the certificate
-\(using ndn-install-pubcert command\), you can enable automatic configuration of the default
-route using your key.  To do so, you need to run the following commands once:
-
-  # extract public key from ccnx user
-  sudo HOME=${ccnxdir} ndn-extract-public-key > /tmp/ccnx.pem
-
-  # sign public key of the ccnx user
-  ndn-sign-key -i \"ccnx-autoconfig\" /tmp/ccnx.pem
-
-  # install certification of the public key
-  sudo HOME=${ccnxdir} ndn-install-pubcert /tmp/ccnx.pubcert
