+Mathematics / LaTeX
+~~~~~~~~~~~~~~~~~~~
+
+Haddock supports LaTeX syntax for rendering mathematical notation. The
+delimiters are ``\[...\]`` for displayed mathematics and ``\(...\)``
+for in-line mathematics. An example looks like this: ::
+
+  \[
+  f(a) = \frac{1}{2\pi i}\oint_\gamma \frac{f(z)}{z-a}\,\mathrm{d}z
+  \]
+
+If the output format supports it, the mathematics will be rendered
+inside the documentation. For example, the HTML backend will display
+the mathematics via `MathJax <https://www.mathjax.org>`__.
