AsciiDoc is a human-readable document format that is semantically equivalent to DocBook XML, but uses a plain-text markup language. It's designed for writing notes, documentation, articles, books, ebooks, slide decks, web pages, man pages and blogs. AsciiDoc files are typically written with a text editor and then processed into various output formats such as HTML, PDF, EPUB, and DocBook XML using an AsciiDoc processor. The format emphasizes readability and ease of writing, making it a popular choice for technical writers and developers. AsciiDoc supports features like tables, lists, cross-references, and includes, allowing for the creation of complex and well-structured documents. The plain text nature of AsciiDoc makes it ideal for version control systems like Git, as changes are easily tracked and diffed. It is often used in software documentation projects, where maintainability and collaboration are crucial. AsciiDoc is also supported by various static site generators and documentation tools, further enhancing its versatility.
