{{caution|Use of this template's functionality may inhibit maintenance of TemplateData until Phabricator ticket {{phab|T314970}} has been resolved and the Manage TemplateData widget functions correctly.}}

{{tlx|TemplateData|''TemplateData content''}}

This template is intended for inclusion in template documentation, either within /doc or the {{tag|noinclude}} tags of a template. It displays any content, intended to be TemplateData or transclusions of TemplateData from other locations, along with standard headers. If parameter 1 is not specified, this template detects whether the subpage /TemplateData exists for the current template, and provides a standardized header based on its existence:

* /TemplateData exists - the template automatically transcludes the TemplateData subpage into the documentation to be used by the visual editor and other tools that read the machine code, including all of the proper headers, along with links to edit and view the page and its history.

* /TemplateData does not exist - the template creates a section header with links to create the TemplateData subpage and preloads basic TemplateData code that is usable by Wikipedia tools.

==Examples==
===Default /TemplateData subpage exists===
{{tlx|TemplateData}}

{{TemplateData}}

===Missing /TemplateData subpage===
{{tlx|TemplateData}}
