-This theme supports rendering beautiful math in inline and display modes using [KaTeX](https://khan.github.io/KaTeX/) engine. You just need to surround your math expression with `$$`, like `$$ E = mc^2 $$`. If you leave it inside a paragraph, it will produce an inline expression, just like $$ E = mc^2 $$.
+This theme supports rendering beautiful math in inline and display modes using [MathJax 3](https://www.mathjax.org/){:target="\_blank"} engine. You just need to surround your math expression with `$$`, like `$$ E = mc^2 $$`. If you leave it inside a paragraph, it will produce an inline expression, just like $$ E = mc^2 $$.
 
 To use display mode, again surround your expression with `$$` and place it as a separate paragraph. Here is an example:
 
 $$
 \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)
 $$
 
-Note that [KaTeX](https://khan.github.io/KaTeX/) is work in progress, so it does not support the full range of math expressions as, say, [MathJax](https://www.mathjax.org/). Yet, it is [blazing fast](http://www.intmath.com/cg5/katex-mathjax-comparison.php).
+Note that MathJax 3 is [a major re-write of MathJax](https://docs.mathjax.org/en/latest/upgrading/whats-new-3.0.html){:target="\_blank"} that brought a significant improvement to the loading and rendering speed, which is now [on par with KaTeX](http://www.intmath.com/cg5/katex-mathjax-comparison.php){:target="\_blank"}.
