Add a language version to an SXA site
You can use a default script to deliver your SXA site in a different language version. The SXA language manager adds the language to all site items and copies the field values from the selected source language to a new version in the target language.
To add a language version of your site:
In the Content Editor, right-click the site item, click Scripts, and click Add Site Language.
In the Add language to the site dialog box, in the Existing Language field, enter the source language and in the New Language field, enter the target language.
Click OK to start the script. All site items now have new versions in the target language.
