Markdown markup language can be used in selected text inputs of the ReCodEx web application. Markdown is simple and lightweight and can be used for quick formatting of your input. ReCodEx uses [Markdown-it](https://github.com/markdown-it/markdown-it) parser with [Katex](https://github.com/waylonflinn/markdown-it-katex) extension that allows including math in LaTeX syntax.

A lot of cheatsheets and tutorials have been made on displaying Markdown features, here are few of them:
