+Download and install hyphenation patterns from CTAN for different languages,

+etc.).
+
+If there are multiple pattern files for a language (and so the filename is not
+"hyph-LANG.pat.txt"), you must specify the respective part of the filename,
+e. g. "en-gb" or "en-us". In this case, the extra part ("-gb" or "-us") is
+automatically removed.
+
+If you are not sure, simply specify the language code ("en" in this example);
