+#!/usr/bin/env bash
+
+# This i3status wrapper allows to add custom information in any position of the statusline
+# It was developed for i3bar (JSON format)
+
+# The idea is to define "holder" modules in i3status config and then replace them
+
+# In order to make this example work you need to add
+# order += "tztime holder__hey_man"
+# and 
+# tztime holder__hey_man {
+#        format = "holder__hey_man"
+# }
+# in i3staus config 
+
+# Don't forget that i3status config should contain:
+# general {
+#   output_format = i3bar
+# }
+#
+# and i3 config should contain:
+# bar {
+#   status_command exec /path/to/this/script.sh
+# }
+
+# Make sure jq is installed
+# That's it
+
+# You can easily add multiple custom modules using additional "holders"
