+## Math typesetting with Katex
+
+Download the latest release from <https://github.com/KaTeX/KaTeX/releases>. Unpack and place the resulting "katex" directory in the root `assets/vendor` directory.
+
+The resulting path should be `assets/vendor/katex`. Then set the `math` param to true and write some math to be typeset.
