This template adds an information banner to assist readers in understanding an {{Interlanguage link}}. Up to two parameters may be supplied:

The first (and only) unnamed parameter, |sec= and |section= change the first words. By default they are "This page". If the parameter is "y" or "true" then the words will be "This section". Any other value simply replaces the word "article".

By default the message is displayed across the width of the page. If |small=left is supplied then the box will be narrow on the left-hand side. This only works in sections, boxes applying to the whole page cannot be rendered small.
