 This module exposes internal pandoc functions and utility
 functions.
 
+The module is loaded as part of the `pandoc` module and available
+as `pandoc.utils`. In versions up-to and including pandoc 2.6,
+this module had to be loaded explicitly. Example:
+
+    local utils = require 'pandoc.utils'
+
+Use this for backwards compatibility.
