+# markdown-it-katex
+
+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
+```
+
+Include the KaTeX stylesheet in your html:
+```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:
+https://github.com/sindresorhus/github-markdown-css
+
+## 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:

+$\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t}  = \vec{\mathbf{0}}$ |  curl of $\vec{\mathbf{E}}$ is proportional to the rate of change of $\vec{\mathbf{B}}$
