{V\'{i}t Star\'{y} Novotn\'{y} {Markdown themes in practice} {The Markdown package for \TeX\ supports user-defined themes that enable \TeX{}nicians to tailor the presentation of Markdown and \YAML\ content on the page. In this talk, I will show the current state of Markdown themes using the example of \LaTeX\ templates that I developed for the International Software Testing Qualifications Board (\acro{ISTQB}). Attendees will leave with actionable steps to create or modify Markdown themes for \LaTeX, and insights into extending these principles to other \TeX\ engines.}
