Technical Guide to Yandex Flavored Markdown (YFM) Yandex Flavored Markdown (YFM) is an open-source extension of standard Markdown designed to build complex, enterprise-grade documentation ecosystems. Developed by Yandex and powered by the Diplodoc toolchain, YFM bridges the gap between simple text formatting and the robust requirements of technical writers, including conditional rendering, modular reusability, and rich UI components.
Here is a comprehensive overview of YFM, its core syntax enhancements, and how it optimizes documentation workflows. Why Yandex Flavored Markdown?
While standard Markdown is excellent for simple README files, it lacks native support for complex documentation needs like tabs, warning alerts, variables, and multi-file inheritance.
Technical authors traditionally had to choose between easy-to-read Markdown or heavy, feature-rich formats like DITA or Sphinx (reStructuredText). YFM offers a middle ground: it retains the human-readable simplicity of Markdown while adding powerful semantic extensions required for large-scale documentation. Key Features and Syntax Extensions
YFM builds upon standard CommonMark compliance and introduces unique plugins for advanced documentation layout and logic. 1. Variables and Conditional Rendering ({% … %})
YFM supports text-replacement variables and conditional statements directly within the text. This allows teams to manage multiple versions of documentation (e.g., Cloud vs. On-Premise) from a single source file.
# Product Installation Welcome to the documentation for {% if product == “enterprise” %} Enterprise {% else %} Standard {% endif %} Edition. For support, contact us at {{ support_email }}. Use code with caution. 2. File Inclusions (Inlines and Blocks)
To prevent repeating documentation across multiple pages, YFM allows you to dynamically include the contents of one file inside another using the {% include %} syntax.
