+# Some code taken from `nickserv.pl' for convenience.
+# Credits Sami Haahtinen / ZaNaGa
+#
+
+# Don't forget to create the necessary chatnets in your irssi config file.
+#
+# Example:
+# ....
+# {
+# address = "irc.undernet.org";
+# chatnet = "Undernet";
+# port = "6668";
+# autoconnect = no;
+# }
+# .....
+#
+#
+# Then connect with the server like this:
+# /server undernet (or set autoconnect to yes)
+
+# Make sure you fill in *all* necessary information without typos.
+#
+# Files you need to edit after first run:
+# x.users -> For your x user/pw information.
+# x.channels -> Channels to join after authing. (optional)
+#
+# Use /xrehash to reload if you edit the files.
+#
+# Var:
+# my (%masks) -> See help there.
+
+# Tested with X versions
+# Undernet P10 Channel Services II Release 1.1pl7
