AsciiDoc is the heavyweight of plain-text documentation: == headings, [source] blocks and tables that scale to entire books. It powers the Git and Linux-kernel ecosystems, where Asciidoctor renders it to every output imaginable.
Typical use: Convert AsciiDoc when docs need to move into Word, Markdown pipelines or HTML sites without losing structure.
About the AsciiDoc format
AsciiDoc is what happens when lightweight markup grows up. Where Markdown stops at bold and lists, AsciiDoc carries title pages, multi-level sections, callouts, admonitions, xrefs and real table syntax — enough to author entire technical books without leaving plain text. The Git and Linux-kernel documentation ecosystems standardized on it, rendered through Asciidoctor.
The format's weakness is tooling gravity: AsciiDoc converters outside the Asciidoctor/Ruby world are scarce, which is exactly where Pandoc fills the gap. Converting to Word hands manuscripts to editors who live in Office; converting to Markdown feeds modern docs sites. The section structure and tables survive the trip.
