Quarkdown is a modern Markdown-based typesetting system, designed around the key concept of versatility, by seamlessly compiling a project into a print-ready book or an interactive presentation. All through an incredibly powerful Turing-complete extension of Markdown, ensuring your ideas flow automatically into paper. Born as an extension of CommonMark and GFM, the Quarkdown Flavor brings functions to Markdown, along with many other syntax extensions. Possibilities are unlimited thanks to an ever-expanding standard library, which offers layout builders, I/O, math, conditional statements and loops. Not enough? You can still define your own functions and variables — all within Markdown. You can even create awesome libraries for everyone to use. This out-of-the-box scripting support opens doors to complex and dynamic content that would be otherwise impossible to achieve with vanilla Markdown. Combined with live preview and fast compilation speed, Quarkdown simply gets the work done.
