<p>I used LaTex to write math or chemical formulae and publish them online.</p>
<p>Dendron supports <a href="https://katex.org/">KaTex</a>. Here is a <a href="https://katex.org/docs/supported.html">list of TeX functions</a> supported by KaTeX</p>
<p>Obsidian render LaTex using <a href="https://www.mathjax.org/">MathJax</a>, so I can only use chemistry syntax supported by <a href="https://mhchem.github.io/MathJax-mhchem/">mhchem</a></p>
