Text

This file is saved in a plain text format. You can open and view the contents of this file using a text editor.

Definition

Text file created using one of several possible dialects of the Markdown language; uses plain text formatting but includes inline text symbols that define how to format the text (e.g., bold, indentations, headers, table formatting); designed for authoring plain text documentation that can be easily converted to HTML.

More Information

MD files are not only useful for HTML documentation systems, but also for source code version control. This is because the files can be compared against historical revisions in human-readable text (whereas a binary format cannot be easily compared). Projects created with GitHub, a popular online version control system, often use a file named README.md, which contains the readme for the project.

John Gruber, the developer of Markdown, has created a Perl program for converting Markdown to HTML. The program, called "Markdown," is available at the Daring Fireball website.

NOTE: Markdown files also used the .MARKDOWN extension.
