The original name of the template that was copied. (Note: this parameter will not default to the page name. This is deliberate to avoid potentially misleading or broken links in the event that the names are different between our wiki and the original.)
2 or from
optional
The name of the wiki that the template was copied from (defaults to "Wikipedia"). If this is a recognized name, an interwiki link will be created.
3 or link
optional
The URL of the wiki for linking. This should be the entire URL of the main page, or if the template parameter is specified, the URL of the copied template, less the trailing /Template:... portion.
