Hello, I'm trying to create a site using mediawiki and ineed to have a clickable button at one page. I've tried to include a text provided here https://commons.wikimedia.org/w/index.php?title=Template:Clickable_button/doc&action=submit
and it resulted in the text Template:Clickable button on the page. Apparently, my mediawiki doesn't contain a template for clickable buttons. The question is: where can I take the code for this template so that my clickable button works? Thank you
