# Math typesetting using KaTex for gitbooks

This is a fork of the orginal plugin-katex but works with newer versions of gitbook.

### Install

Use it for your book, by adding to your book.json:

```
{
"plugins": ["enhanced-katex"]
}
```

then run `gitbook install`

.

### Usage

Inline math is used with double $ signs:

```
$$ a^2 + b^2 = c^2 $$
```

Block math is used with tripple $ signs:

```
$$$ \int \frac{1}{1+x^2}\, dx = \arctan x + C. $$$
```
