This template is used on translated template messages, to avoid getting these on image pages and to lead to use the master template (NOT the translated one).
All categorization of translated tags is done through this template. It will add a local category based on the template's language and a general maintenance category based on the type of template it is. For the latter, you must supply the "type" as the first parameter. See Template:Translated tag/local category-en for possible values (or view template code). All templates lacking this will end up in Category:Translated templates needing categories (however they will still be in a proper language-based category). If none of the available options match the template in question just leave it as {{translated tag}}.
Add one of the following as the first parameter:
cleanup
license
marker
problem
restriction
header
infobox
navigational
user
protection
source
documentation
localisation (this is a special case for translations that can be used directly, note the UK spelling)
For example, you would change {{translated tag}} to {{translated tag|cleanup}} for cleanup templates.
TemplateData is a way to store information about template parameters (the description of those and of the whole template) for both humans and machines. It is used by VisualEditor and possibly other tools like Upload Wizard.
Existing template documentation
At Wikimedia Commons, it is recommended to use {{TemplateBox}} with either useTemplateData=1 or useTemplateData=only on the /doc subpage and transcluding it with {{Documentation}} into the template. <nowiki>-tags can be wrapped around the arguments, if required, to avoid templates being expanded.
Newly created template documentation and imports
Another option, especially for imported templates, or for users with JSON experience, is placing raw <templatedata>-tags into the Wikitext of the template, as described in various Wikipediae.
