remark is a popular free and open source tool that transforms markdown with plugins. Markdown is a markup language that often feels more natural to type than HTML. Plugins can inspect and change markdown.

• to learn markdown, see this cheatsheet and tutorial
• we follow CommonMark by default (GFM with remark-gfm, MDX with remark-mdx)
• we use micromark for parsing and mdast as the syntax tree
• to find plugins, see remarkjs/awesome-remark, the list of plugins, and the remark-plugin topic

remark is part of the unified collective, which brings together organisations that work with content as structured data.
