-## Localization updates
-
-There are three date formats:
+## Localizated variants
 
-- A date string format (using [babel](https://github.com/python-babel/babel/tree/master/babel)
-- A ISO format *(YYYY-mm-dd)*
-- A time ago format (using [timeago](https://github.com/hustcc/timeago)
+The plugin uses [babel](https://github.com/python-babel/babel/tree/master/babel) and [timeago](https://github.com/hustcc/timeago) to provide different date formats:
