mdast-util-gfm adds support for GitHub Flavored Markdown (GFM) to unified's Markdown Abstract Syntax Tree (mdast). It parses GFM features like tables, task lists, strikethrough, autolink literals, and footnotes, transforming Markdown text into a structured mdast representation. Integrate this utility with remark to enable comprehensive GFM parsing and manipulation, allowing for more robust Markdown processing and analysis of GFM-specific elements within your documents.
