 =head1 DESCRIPTION
 
 This module tries to get translated lyrics from
-L<http://lyricstranslate.com>. It does a search for a translation of
-the given artist and song title from any language to English, and
-returns the contents of the first result found.
-
-This is a very basic implementation of the concept and it should be
-improved in future versions (for example supporting multiple
-destination languages).
+L<http://lyricstranslate.com>. It searches for a translation of the
+given artist and song title from any language to a requested language
+(which defaults to English), and returns the contents of the first
+result found.
 
 It is recommended to use the module directly, as using it via
 L<Lyrics::Fetcher> loses empty lines between parahraphs.
 
+The target language can be specified as either a number or a string.
+If a string is given, it is looked up in the hash
+C<%Lyrics::Fetcher::LyricsTranslate::LANGUAGES> which maps language
+names to their numerical identifiers. The hash was generated from the
+website, and it might be outdated.
+
+The target language is passed as the third argument to the B<fetch>
+method. If using the module via L<Lyrics::Fetcher>, the target
+language cannot be set and defaults to English.
