A screenshot of the TemplateData editing tool
The TemplateData editing tool, on a page that contains no TemplateData yet.

The editor allows you to add template parameters and to set the most common attributes. If the page you edited already contains a block of TemplateData, then the information already documented will automatically be shown when you open the correct page in the TemplateData editor. In the first box, you can add or update a short description of the template in plain text. After that, you can use the "Add suggested parameter(s)" and "Add parameter" buttons to document the names and attributes of the parameters that the template uses.
