# Syntax

Diplodoc uses **Yandex Flavored Markdown (YFM)** syntax — a Markdown dialect with an additional set of tools for transforming Markdown into HTML and building documentation projects.

Features:

* Compatibility with the [CommonMark Spec](https://spec.commonmark.org/) standard.
* The ability to [connect](https://diplodoc-platform--docs.viewer.diplodoc.com/en/plugins/external.md) third-party markdown-it plugins.
* Security: HTML is escaped by default.
* Dynamic validation.
* Building a documentation project.

The following are used for formatting:
* [basic markup](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/base.md);
* [links](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/links.md);
* [lists](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/lists.md);
* [simple](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/tables/gfm.md) and [multiline tables](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/tables/multiline.md);
* [notes](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/notes.md);
* [cuts, tabs, and radio buttons](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/interactive-elements/index.md);
* [images and videos](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/media.md);
* [code fragments](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/code.md);
* [tooltips](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/term.md);
* [variables](https://diplodoc-platform--docs.viewer.diplodoc.com/en/syntax/vars.md).
