Wikibase.cloud lets you create MediaWiki wikis with Wikibase. Here's everything you need to know about creating and managing a wiki.
Creating a wiki[edit]
Once you've verified your email, click the "+" button on the dashboard page to create a new wiki.

Next, fill out the "Create a wiki" form. You can choose your own site name and initial MediaWiki user name.

Site domain[edit]
The site domain is your site's name as it appears in a browser. You can select from two options:
- Free subdomain: If available, the name you choose becomes a subdomain of wikibase.cloud. It must be at least 20 characters long.
- Example:
my-amazing-library-site.wikibase.cloud
- Custom domain: If you have an existing domain name you'd like to use, enter it here. In DNS, that name should be a CNAME pointing to:
sites-1.dyna.wikibase.cloud.
After you click "Create wiki", the settings page for your new wiki will appear.
Settings page[edit]
On the Settings page you will see two tabs: "Wiki settings" and "Features".
Wiki settings tab[edit]
In the settings tab you can control various aspects of your new wiki, such as the default skin and logo. You can also delete your wiki from this page.

- Details: This panel displays important information about your wiki for your reference.
- Skin: Here you can choose your wiki's skin -- your site's general appearance.
- Logo: You can set the logo that appears in the top corner of every page on your wiki. Uploaded images should be square -- they will be resized into a 135-pixel by 135-pixel square.
- Registration: By turning this switch on you disable open registration on your wiki, requiring new accounts to be approved by users of your site who have the "bureaucrat" right.
- Wikibase options: Proceed with caution! Changing these values may cause problems with your wiki.
- Value lengths: These fields control the length (in characters) of strings and of monolingual text fields. Lengths can range from 400 (default) to 2500.
- Multilang lengths: This field controls the length (in characters) of multilanguage fields such as labels and descriptions. Lengths can range from 250 (default) to 2500.

- Delete site: If you would like to delete your site, click the "Delete site" button. Be careful: deletion is irreversible! You will be asked to confirm your choice, after which your site will be deleted forever.
Features tab[edit]
On the Features tab you can manage available Wikibase features.
Mapping properties to Wikidata[edit]
This feature allows you to define local properties to be mapped to properties on Wikidata.

Depending on the property you map to, a mapped property may enable extra functionality:
$wgLexemeLanguageCodePropertyId
is set by Property P218$wgWBRepoSettings['formatterUrlProperty']
is set by Property P1630$wgWBRepoSettings['canonicalUriProperty']
is set by Property P1921
Mapping items to Wikidata[edit]
This feature allows you to define local items to be mapped to items on Wikidata.

Lexemes[edit]
Here you can enable Lexemes for your Wikibase.

Once Lexemes are enabled, enter your wiki; you will see the New Lexeme option in the sidebar.

You can make use of the Property mapping feature to set a property that should be used for Lexeme language codes. (The corresponding property on Wikidata is P218.)
Using your wiki[edit]
To enter your wiki, navigate to the dashboard and click the icon next to the wiki you'd like to enter.
