This repository contains polyfills for features from the MathML specification, relying only on MathML Core and other web technologies natively implemented in browsers. See discussion on wiki

The set of polyfills, as referenced by all-polyfills.js can be used as a simple script element in HTML pages, as module for ES6 or as an NPM package. See README in rollup.
