What is a .AsciiDoc file?

ASCIIDOC is a plain-text markup format for technical documentation, richer than Markdown and able to produce books, web pages and man pages.

Did you know: AsciiDoc was designed to capture everything the DocBook XML standard could express while staying as readable as an ordinary text file.
AsciiDoc was created by Stuart Rackham in 2002, and the popular Asciidoctor toolchain now renders it to HTML, PDF and EPUB.
It is widely used for software documentation - GitHub and GitLab both render .adoc files directly in the browser.
