MarkDown is a text-only format used to create books, web pages, manuals and other types of documents. Besides being easy to read, MarkDown can serve as the base for exporting to other document formats such as HTML, ODF, DOC, PDF and ebook (EPUB, MOBI...). It is a great tool for authors, technical writers, creative writers and content developers. CommonMark is a new well-formed standard for the old MarkDown spec. It is set to replace and overtake MarkDown. StackOverFlow.com and other sites have already adopted it.

CommonMark Ready Reference provides a full tutorial, hacks collection and a ready reference for the new standard. CommonMark was one of the reasons that the author was able to write and design 21 books in one year. Incidentally, this is the first-ever book on CommonMark. You will be buying a piece of history! This book's covers are designed like a quick reference card.
