+## KaTeX
 You can enable [KaTeX](https://katex.org/) (math typesetting) by including
 `math: true` in your content files. Or you can enable it globally by setting
 `math` to `true` in your project config.
 
+Hugo introduces tags when it sees newlines which breaks KaTeX block
+environments. The theme has a `math` shortcode to circumvent this issue:
+```md
+{{< math >}}
+\begin{pmatrix}
+a & b \\
+c & d
+\end{pmatrix}
+{{< /math >}}
+```
