If you are here to start a new language edition of a project, you can find all information on Help:Manual. Please be aware of the local policy.

Some important rules:

• You need a valid language code (explained in the manual). If you don't, you can apply for one, or use the non-Wikimedia wiki Incubator Plus 2.0.
• Starting a test wiki here doesn't mean it will later be automatically accepted by Wikimedia; you need it to be approved by the Language committee first. See Requests for new languages for more information.
• Please respect the naming conventions for the test language, to help future migrations of pages to an actual wiki project. All of your test pages (including templates and categories) need to be named uniquely (by using a prefix) and consistently.

If you have knowledge of a language which currently has a test wiki here, you are strongly encouraged to contribute to that test wiki.

Please give all pages you create a correct prefix. More information about prefixes.
