-- Only works with SVN revision 50605 or later of the
-  MediaWiki core
-
-
-
-Key issues at the moment:
-* Seems to want to store a copy of the localization updates in each local database.
-We've got hundreds of wikis run from the same installation set; we don't want to multiply our effort by 1000.
-
-* It doesn't seem to be using available memcached stuff; unsure yet whether this is taken care of
-by the general message caching or if we're going to end up making extra hits we don't need.

+== Localisation Update ==
+Localisation Update extension can update the MediaWiki messages at any time,
+without needing to upgrade the MediaWiki software.
+
+For more information see:
+ https://www.mediawiki.org/wiki/Extension:LocalisationUpdate
+
+== Installation ==
+1. Add the following to LocalSettings.php of your MediaWiki setup:
+
+ require_once "$IP/extensions/LocalisationUpdate/LocalisationUpdate.php";
+ $wgLocalisationUpdateDirectory = "$IP/cache";
+
+2. Create a cache folder in the installation directory, and be sure the server
+has permissions to write on it.
+
+If localization updates don't seem to come through, you may need to run,
+
+ php maintenance/rebuildLocalisationCache.php --force.
+
+3. Whenever you want to run an update, run,
+
+ php extensions/LocalisationUpdate/update.php
+
+For detailed help, see:
+
+ php extensions/LocalisationUpdate/update.php --help
+
+4. If you are on Unix like system, you should add LocalisationUpdate to
+crontab:
+
+ crontab -e
+ # Add the following line
+ @daily php /path/to/your/wiki/extensions/LocalisationUpdate/update.php --quiet
