About CommonMark

Despite its phenomenal success online and widespread adoption even beyond the Internet, one problem that continued to bug Markdown was the lack of a proper standard. Today, CommonMark ( is replacing Markdown as the de facto standard for low-markup text. CommonMark hit the ground with a well-defined standard from Day 1 and is set to replace and overtake MarkDown. and other sites have already adopted it. As someone has described, CommonMark is MarkDown done right. It is highly compatible with the original MarkDown and resolves most of its ambiguities. This book provides a tutorial, hacks collection and a ready reference for the new standard.

The Executables

Anyone can build CommonMark from its source code available at I built my CommonMark executables (for Linux and Windows) using version 0.29. You can use them at your own risk.

These executables were built on a 9-year-old OS. While they are fully functional, I would like you to build them on your computer to avoid compiler bugs and for maximum safety.

Video Demo

This video shows how the back cover looks. (The reference card on the paperback is also NOT lopsided. The screenshot is an early draft. I am not going to fix it.) The book is also not as big. I doubt if it even has a spine. I cannot get the paperback ordered as India is under lockdown.
