+# _locales folder
+This folder contains the extension strings in various languages.
+
+*** note
+**Warning:** The only file that should be modified in this folder is the
+`en/messages.json` file.
+
+After modifying that file, it should get uploaded to Crowdin so it can be
+translated there, and afterwards the `downloadTranslations.bash` script at the
+`//tools/i18n` directory can be run to generate all the other subfolders.
