AsciiDoc is a human-readable document format, semantically equivalent to DocBook XML, but using plain-text mark-up conventions. AsciiDoc documents can be created using any text editor and read “as-is”, or rendered to HTML or any other format supported by a DocBook tool-chain, i.e. PDF, TeX, Unix manpages, e-books, slide presentations, etc.[1] Common file extensions for AsciiDoc files are txt(as encouraged by AsciiDoc's creator) and adoc.[2][3]


AsciiDoc was created in 2002 by Stuart Rackham, who published tools (‘asciidoc’ and ‘a2x’), written in the Python programming language to convert plain-text, ‘human readable’ files to commonly used published document formats.[1]

A Ruby implementation called ‘Asciidoctor’, released in 2013, is in use by GitHub[4] and GitLab.[5] This implementation is also available in the Java ecosystem using JRuby and in the JavaScript ecosystem using Opal.js.

Some of O'Reilly Media's books and e-books are authored using AsciiDoc mark-up.[6]

Most of the Git project documentation is written in AsciiDoc.[7]


The following shows text using AsciiDoc mark-up, and a rendering similar to that produced by an AsciiDoc processor:
