This page describes the currentmulti-lingual policy on MediaWiki.org.

TheHelp: namespace contains a set ofpublic domain help pages. The aim is to provide a basic set of help pages that may be imported into new wikis covering the basic editing and usage instructions. These should be translated into as many languages as possible.
Table editing/example - useTable editing example orExample of table editing instead).This system will be compatible with the plannedautomated import/export of Help pages, but may need a bit of working around to export/import non-English pages in the interim.
We use theTranslate extension for hundreds of pages.These use the subpage convention, with {{#translation:}} for categories.
The system is recommended at least for most visited pages and all new help, manual and (main) extension pages, but no policy has been established on this yet.
You can request a page to be added to translation by preparing it for translation, then a translation administrator will have to enable it (see the tutorialHow to prepare a page for translation); otherwise, ask directly to one of thetranslation administrators to do it.
{{Languages}} template, which automatically creates links to all available translations.The pages with existing translations are usually worth being made into translatable pages.Prepare the (English) root page for translation (seethe Translate extension section) and, as soon as it's marked for translation, manually import the old translations from the history of subpages to the translation units (by clickingTranslate this page).The new featureSpecial:PagePreparation +Special:PageMigration facilitates this (currently available only for translation administrators).
A list of pages translated with the old system, to be migrated to the new, is in the works atProject:Language policy/Migration list.
More detailed instructions:
<translate> tags etc.) following the page translation tutorial linked above; then edit the migration list, writing next to the page's title that you've done it.The English version of our front page is located atMediaWiki. Translated versions are located at MediaWiki/code, wherecode is the language code (e.g.MediaWiki/fr). Please seeTemplate:Main page for content of main page; you can translate it there.
Importantly, the rules about language codes (seebelow) should be followed here as well.
Apart from the Main Page, no policy has yet been decided about other namespaces. For the time being, if you would like to create translations for pages in other namespaces then please do so as described for the Help: namespace, however content may be moved or deleted depending on the policy that is eventually adopted.
For some discussions, seeLanguages andTranslate extension at the village pump.
Note that the rule that English content should not be placed in sub-pages does not apply to other namespaces. This is one of the issues that needs resolving.
Throughout MediaWiki.org you should use the language codes specified by the MediaWiki software when creating language-specific content (seeNames.php for the full and up-to-date list).
Please also bear the following in mind:
zh-yue has been replaced withyue). In these cases only the most recent code should be used.zh-hans) is discouraged and should be added into the main page (e.g.zh) where possible.
