Convert TXT MARKDOWN to MDOWN

Markdown Documentation files, often stored with a TXT extension, are utilized for writing plain-text formatted documents that are easy to read and convert to HTML. Originating in 2004 by John Gruber and Aaron Swartz, Markdown's intent was to create a simple syntax for writing web-based documents. It is widely adopted in software development, documentation, and content management systems due to its readability and ease of use. These files facilitate collaborative work and version control, making them indispensable in modern IT workflows.

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.
