## Math Typesetting

A brief guide to setup KaTeX

Mathematical notation in a Hugo project can be enabled by using third party JavaScript libraries.

In this example we will be using KaTeX

- Create a partial under `/layouts/partials/math.html`
- Within this partial reference the Auto-render Extension or host these scripts locally.
- Include the partial in your templates like so:

    {{ if or .Params.math .Site.Params.math }}
    {{ partial "math.html" . }}
    {{ end }}

- To enable KaTex globally set the parameter `math` to `true` in a project’s configuration
- To enable KaTex on a per page basis include the parameter `math: true` in content files

Note: Use the online reference of Supported TeX Functions

### Examples

Block math: $$ \varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } } $$
