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

Installation

• 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 https://github.com/jmnote/SimpleMathJax.git

• (Optional) If you want to use not CDN but local mathjax scripts, you can use git clone recursive.

$ git clone --recursive https://github.com/jmnote/SimpleMathJax.git

• LocalSetting.php

wfLoadExtension( 'SimpleMathJax' );
