 ## Configure
 Read config.toml and adapt it to your preferences. Keep in mind that for docker
 use you want to keep log_file="CONSOLE".
+
+## Action Script
+You can configure action script by adding it to config.toml.
+When a new suspicious IP address is detected, the script will be executed. See
+action_script.sh for an example.

+# Example for Linux:
+#   iptables -I INPUT -s $1 -j DROP
+#
+# Example for OpenBSD:
+# Having a table in pf.conf:
+#   table <blacklist> persist file "/etc/blacklist"
+#   block drop in quick from <blacklist> to any
+# then add/delete dinamically:
+#   pfctl -t badhosts -T add $1
+#   pfctl -t badhosts -T delete $1
