$\KaTeX$ is used for rendering LaTeX math expressions. It can be enabled per page by setting `math` to `true` in the page front matter.
```yaml {filename="Markdown"}
---
title: "My Page with LaTeX"
math: true
---
```
When enabled, the scripts, stylesheets and fonts from KaTeX will be included automatically in your site. You can start using LaTeX math expressions in your Markdown content.
## Example
Both inline and separate paragraph LaTeX math expressions are supported in the Markdown content.
### Inline
```markdown {filename="page.md"}
This $\sigma(z) = \frac{1}{1 + e^{-z}}$ is inline.
```
This $\sigma(z) = \frac{1}{1 + e^{-z}}$ is inline.
