The SimpleMathJax extension enables MathJax, a Javascript library, for typesetting TeX formula in MediaWiki inside math environments.


  • git clone in extensions directory
  • Using CDN is recommended. Because it's much faster than using local resources in most cases. ("the benefits of using a CDN")
$ git clone
  • (Optional) If you want to use not CDN but local mathjax scripts, you can use git clone recursive.
$ git clone --recursive
  • LocalSetting.php
wfLoadExtension( 'SimpleMathJax' );
