Creating an automatically appearing Welcome template[edit source]

Hi. I currently run the Oddworld wikia. How do I create a welcome template that automatically appears on user talk pages immediately after the user's first edit? I gained ownership of the wikia prior to most of the major updates; back when templates were still being experimented with and back when the wiki navigation bar was on the left of the pages (to give you an idea of how far back). I always receive automatic (customized) welcome messages from wiki staff whenever I make my first edits on other wikis. How can I customize or create the template to add images, boxes, etc. to them and still have them instantly appear on new user talk pages? I would really appreciate the help. --RadicalEdward2 (talk) 15:50, January 2, 2013 (UTC)

You need to edit certain MediaWiki pages.--The doubleplusgood Alficiro! 05:09, April 8, 2017 (UTC)
