WP:twinkle

edit
In response to your question, it's one of the vandalism templates, which I got via pulldowns using wp:twinkle. The page has all the install stuff you need. I *highly* recommend Twinkle for anti-vandal use. Feel free to ask me any questions, of course. --KNHaw (talk) 05:35, 22 January 2018 (UTC)Reply
FYI, Your signature links to the talk page at User_talk:Example. I think you need to modify it to directly link here ("User talk:Extarys") instead of "User Talk:$1".
