See the README in the math subdirectory for more info on setting up the
low-level conversion tools.
MathML support:
If you prefer MathML rather than images you can use LaTeXML to convert the
math tags to MathML. To use that feature you have to enable LaTeXML by setting
$wgUseLaTeXML = true;
It is possible to choose LaTeXML as default option (for anonymous user) by setting
$wgDefaultUserOptions['math'] = MW_MATH_LATEXML;
in the LocalSettings.php file.
The LaTeXML option requires php5-curl to be installed. Without php5-curl no proper
error handling can be guaranteed.
MathJax configuration:
Client-side configuration of MathJax can be done by specifying a mathJax.config
table, which takes a table as described in:
