About Twitter cards

Twitter describes this feature like this:

“Twitter cards make it possible for you to attach media experiences to Tweets that link to your content. Simply add a few lines of HTML to your webpages, and users who Tweet links to your content will have a "card" added to the Tweet that’s visible to all of their followers. It would be really nice for articles, images, videos - everything linked from Wikimedia on Twitter could have a nice little preview on Twitter. The documentation is at Twitter cards - basically it involves adding some meta tags around existing content server-side.”

Installation

• Download and move the extracted TwitterCards folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/TwitterCards
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'TwitterCards' );
  

• Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
