Thread:Project:Support desk/Adding support for an "unrecognised" language/reply

If you want to do it just on your wiki, perhaps mw:Extension:Fun_MediaWiki_Languages could perhaps be used as an example for what to do (I'm guessing, I haven't actually looked at that extension).

However, it would probably be better to add translations for this language at translatewiki.net, then your translation can be used by all MediaWiki installs.

You may also be interested in making your Balinese wiki-dictionary as a wiktionary project. If so, see https://incubator.wikimedia.org/wiki/Wt/ban
