To include a template in this category, add [[फलकम्:फलकं वर्गः]] to the <includeonly> section at the bottom of the template's /doc subpage if such a page exists. Otherwise, add <noinclude>[[फलकम्:फलकं वर्गः]]</noinclude> to the end of the template code, making sure it starts on the same line as the last character of the code.
