+          ### Action Required
+          You are adding or updating English content so please take the following actions for other languages.
+          - If you add new content under `website/content/en` or targets of the symbolic links in the same directory, please replicate it in the corresponding directories of all other languages. (e.g. If you create `website/content/en/blog/new-post.md`, you should copy it to `website/content/ja/blog/new-post.md`, etc.)
+          - If you update the content in the same location, please perform the following actions for the corresponding content in other languages.
+            - If the content has not been translated yet, replace the files with the updated English version.
+            - If the content has already been translated, include a note suggesting that users check the English page for the most recent updates.
