+# Usage:
+
+# edit your theme, find the line beginning:
+#
+#    prompt = "..."
+#
+# and add the string `$prompt_additional' somewhere inside it.
+# If using the default: prompt = "[$*] ", then a good value would be:
+#
+#    prompt = "[$*$prompt_additional] "
+#
+# Then add this script to your autorun directory (~/.irssi/scripts/autorun/)
+#
+# You can modify your prompt content by using the '/set_prompt <string>' command,
+# or from scripts by Irssi:signal_emit('change prompt', $string);
