If you are wondering what is a markdown file, it is essentially a plain-text document that uses special symbols to represent formatting. These files commonly use the .md extension and are widely used for documentation, project instructions, README pages, and notes. Developers often prefer them because they are lightweight, easy to edit, and readable even without specialized software. A compatible editor or platform can interpret the symbols and display the content with headings, lists, links, and other formatting. This makes the format practical for maintaining simple technical documentation.
