Template:Template parameter usage/doc

The Template Parameters tool is available for viewing template parameter usage in articles. It works with TemplateData to show the frequency of parameter name usage in a template's mainspace transclusions, along with whether or not each parameter is listed in that template's TemplateData code as a supported parameter. For a required parameter, it can display a list of pages where the template is missing that parameter. The tool also shows commonly used values for each parameter. Each report is updated monthly and does not reflect changes made to articles or to the TemplateData code after the report's generation.

Usage
By default, the template links for the template page:
 * &rarr;

One can enter a template name:
 * &rarr;


 * Parameters are optional

Optional:
 * yes for lowercase "see":
 * Entering Template:Infobox film is accepted (namespace is removed). Editor friendly, using a positional parameter.
 * When 1 is used, "this template" text changes: &rarr;
 * label sets the visible text (does not change the target link):
 * label default &rarr;
 * none &rarr;
 * for &rarr;
 * FooBar &rarr;


 * yes adds the text "based on this TemplateData" to the end of the template (or "based on its TemplateData" if 1 is also used).

The template is included in transclusions of TemplateData header.
