-    To setup vnstat, run `vnstat -u -i en0' (replace en0 with the network
-    interface you wish to monitor).
-
-    You must then create a cron job to update the vnstat database.
-
-    Run `crontab -e' and add the following:
-    0-55/5 * * * * if [ -x #{bin}/vnstat ] && [ `ls #{var}/db/vnstat/ | wc -l` -ge 1 ]; then #{bin}/vnstat -u; fi
+    To monitor interfaces other than "en0" edit #{etc}/vnstat.conf
