# Quarkdown > Quarkdown is a modern, open-source typesetting system that extends Markdown with powerful features inspired by LaTeX. It compiles Markdown-based documents into PDF, HTML, MD, TXT. ## Key Features - **Familiar:** built on the well-known Markdown syntax, for a flat learning curve. - **Elegant:** produces output that matches the quality of industry-leading tools. - **Agent-friendly:** comes with a built-in skill for idiomatic fluency of your coding agents. - **Customizable:** full control over document layout, aesthetics, and properties. - **Secure by default:** a restrictive permission system limits access to system resources. - **Versatile:** a single source compiles to multiple targets. - **Reactive:** low-latency live previews for rapid iteration. The official wiki (100+ subdocuments) compiles in ~2 seconds. - **Reusable:** repeated content can be turned into one-line function calls. - **Easily deployable:** set a CD workflow up in under 3 minutes ([example](https://raw.githubusercontent.com/iamgio/iamgio.github.io/refs/heads/main/.github/workflows/build.yml)). ## Use Cases - Research papers, theses, and academic articles - Books and technical reports - Slide presentations and lectures - Documentation sites and wikis - Knowledge bases and notes ## Learn More For detailed documentation, syntax reference, scripting guides, and technical topics, visit the [Quarkdown Wiki](https://quarkdown.com/wiki/index.md).
