About Markdoc
Markdoc is a Markdown-based syntax and toolchain for creating custom documentation sites. It serves developers and technical writers who need a scalable, extensible authoring framework that grows with their content.

Key Features
Markdoc’s core workflow keeps Markdown familiar while letting you add custom tags, renderers, and validation to meet growing documentation needs:
Familiar syntax
Markdoc extends Markdown so you can keep using standard syntax and tooling.
Easily extensible
You can customize all aspects of the system, including tags, nodes, and renderers.
Built-in validation
You can enforce content rules to catch issues early and maintain consistency across pages.
Declarative composition and flow control
Uses a fully declarative approach to structure content and control flow, reducing bespoke scripting and improving maintainability.
Summary
Best for engineering teams building public docs, developer portals, and internal knowledge bases.
