+Import ISO 639-3 languages
+----------------------------
+
+From Telemeta 1.4, an ISO 639-3 language model has been implemented.
+
+The ISO language table content can be initialized with the official code set.
+Here is a import example where telemeta_crem5 is the SQL database::
+
+    wget http://www.sil.org/iso639-3/iso-639-3_20110525.tab
+    mysql -u root -p
+    load data infile 'iso-639-3_20110525.tab' into table telemeta_crem5.languages CHARACTER SET UTF8 ignore 1 lines (identifier, part2B, part2T, part1, scope, type, name, comment);
+
+If you upgraded Telemeta from a version previous or equal to 1.3, please update the media_items table as follow::
+
+    mysql -u root -p
+    use telemeta_crem5
+    ALTER TABLE media_items ADD COLUMN 'language_iso_id' integer;
+    ALTER TABLE 'media_items' ADD CONSTRAINT 'language_iso_id_refs_id_80b221' FOREIGN KEY ('language_iso_id') REFERENCES 'languages' ('id');
