 ## How to use
 
 Clone this repo to your server and run `sudo ./install.sh`
+To enable logging of all requests from forbidden ips run `sudo ./install.sh --log` instead. This requires rsyslogd to be up and running. If you are unsure - install it without logs.
+All the logs are in the file /var/log/rugov_blacklist/blacklist.log . Keep in mind - if your target could be interesting, you can get a lot of disk space used by this log!
 
 ## What it does
 
-- adds rsyslogd rules in /etc/rsyslog.d/51-iptables-rugov.conf
+- adds rsyslogd rules in /etc/rsyslog.d/51-iptables-rugov.conf (only with --log)
 - makes directory /var/log/rugov_blacklist/
 - puts there all necessary files
 - runs the update process 
 - installs cron script to /etc/cron.daily/rugov_updater.sh
