Convert MD GFM to MDOWN

Markdown (MD) is a lightweight markup language with a file extension MD, commonly used for formatting readme files, documentation, and comments in GitHub repositories. GitHub-Flavored Markdown (GFM) extends the original Markdown's capabilities, adding features like tables, task lists, and auto-linking URLs. Markdown's simplicity and effectiveness in creating formatted text using a plain text editor made it widely adopted in the developer community. GFM, in particular, is optimized for use on GitHub, enhancing collaboration and code documentation.

The MDOWN file extension stands for "Markdown Documentation". It is used for files written in Markdown, a lightweight markup language with plain-text formatting syntax designed by John Gruber and Aaron Swartz in 2004. MDOWN files are commonly employed in software development to create readable and editable documentation, leveraging Markdown's simplicity for formatting text, lists, code blocks, and links. The historical significance of MDOWN lies in its facilitation of seamless documentation, enhancing clarity and accessibility across various platforms while remaining developer-friendly.
