# MathJax Documentation

MathJax is an open-source JavaScript display engine for LaTeX, MathML, and AsciiMath notation that works in all modern browsers, with built-in support for assistive technology like screen readers.

Version 3.0 of MathJax is a complete rewrite of MathJax from the ground up, and its usage and configuration is significantly different from that of MathJax version 2. Use the green menu at the bottom of the sidebar on the left to access the version 2 documentation if you need it.

MathJax is a Sponsored Project of NumFOCUS, a 501(c)(3) nonprofit charity in the United States. NumFOCUS provides MathJax with fiscal, legal, and administrative support to help ensure the health and sustainability of the project. Visit numfocus.org for more information.
