+The format of the message is: "Site: title (duration)"
+
+Available options (see /set $sn):
+- print_own: if true, print info also for own messages
+- site_color: color of the "Site:" part of the message
+- print_rules: decide in which channel/query you want to print the message and how.
+  Three rules exist: '-': don't print, '=': print for you (CRAP level), '+': send a message to the channel/query.
+  The setting in itself is a comma-separated set of rules followed by a regex to apply the rule.
+  Example: '=,+^#foo\$,-bar' which reads like this:
+    '=' is the default rule: show video info only for you by default
+    '+^#foo\$': send the info as a message in the channel #foo
+    '-bar': don't print anything in channels containing 'bar'
+  Hint: to distinguish between channels and queries (for example, print the message for you in channels, but nothing in queries), you can use this setting: '-,=^#'.
