Add Math to your Markdown
KaTeX is fast. This plugin makes it easy to support it in your markdown.
Usage
npm install markdown-it-katex
var md = require('markdown-it')(),
mk = require('markdown-it-katex');
md.use(mk);
Include the KaTeX stylesheet in your html:
<link rel="stylesheet"href="//cdnjs.cloudflare.com/ajax/libs/KaTeX/0.3.0/katex.min.css">
If you're using the default markdown-it parser, I also recommend the github stylesheet:

Examples
Inline
Surround your LaTeX with a single $
on each side for inline rendering.
$\sqrt{3x-1}+(1+x)^2$
Block
Use two ($$
) for block rendering. This mode uses bigger symbols and centers
the result.
$$\begin{array}{c}
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} &
= \frac{4\pi}{c}\vec{\mathbf{j}} \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0
\end{array}$$
Math Syntax Support
KaTeX is based on TeX and LaTeX. Support for both is growing. Here's a list of
currently supported functions:
