An overview of what can currently be done with this extension is found at the English Wikipedia's documentation. ## Installation • If using Vagrant, install with vagrant roles enable math --provision Manual installation • Download and place the file(s) in a directory called Math in your extensions/ folder. • Add the following code at the bottom of your LocalSettings.php: require_once "$IP/extensions/Math/Math.php";

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

## Configuration

Beginning from MW 1.23+ you can use a Mathoid server that uses MathJax to convert texvc input on the server side to MathML+SVG rendering. Mathoid is the rendering mode that is going to be used on future Wikipedia. For that the following settings are recommended:

// Set Mathoid as default rendering option;
$wgDefaultUserOptions['math'] = 'mathml';  Check out Mathoid to find instructions how to run your own Mathoid server. ## List of all configuration settings Setting name Default value Description$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.
$wgMathMathMLTimeout 20 The timeout for the HTTP-Request sent to the MathML to render an equation, in seconds.$wgMathDisableTexFilter false Option to disable the tex filter. If set to true any LaTeX expression is parsed this can be a potential security risk. If set to false only a subset of the TeX commands is allowed. See the wikipedia page Help:Math for details.

## Error reporting

If something is wrong with the math extension you can report that at Phabricator. In addition you should check how your problem relates to the automated unit tests that are generated from the page CoverageTest.
