Flatdoc is a tiny JavaScript library that builds a documentation site directly from Markdown files, without requiring a server-side engine or static site generator. Point it at a Markdown source and it fetches, parses, and renders content into a ready-to-browse doc layout in the browser. It autogenerates a navigation sidebar from headings, supports anchors, and provides a clean default theme that’s easy to restyle. Because it runs client-side, it’s great for small projects, GitHub-hosted docs, or internal references where you want “drop-in” documentation with minimal setup. The library’s footprint and API are intentionally modest, making it simple to customize templates, typography, or color schemes. For teams who value instant docs from a README or single Markdown file, Flatdoc remains a practical, dependency-light choice.

Pretty basic theme for Hugo that covers all of the essentials. All you have to do is start typing.

It includes options for heading depth, bullet style, filtering, slug generation, indentation, and first-heading behavior. It is especially useful for maintaining README files, documentation pages, and generated docs where headings change over time.

reveal-md is a command-line tool that turns Markdown files into browser-based reveal.js presentations.

Themes, syntax-highlighting styles, custom CSS, scripts, templates, favicons, and reveal.js options provide extensive presentation customization. Live reload automatically updates the presentation while the Markdown source is being edited. Presentations can also be exported to PDF or built as static websites, although the project is no longer under active feature development.
