+            Before publishing this ReadAlong on a web site, please convert it to a Web
+            Bundle. This monolithic format is intended for editing and for offline use,
+            but it is not optimized for publication on a web site.
+
+            Use the ReadAlong Studio Editor to convert this to a Web Bundle zip file:
+            https://readalong-studio.mothertongues.org/#/editor
+            Load it in the Editor and download it back using the "Web Bundle" Output Format.
+
+            Publication instructions are in file "www/readme.txt" in the bundle.
