# Wikis and MD files MD files are used in many wikis. For example the DokuWiki is a simple wiki that does not use a backend database. It is simple to install and simple to use. ## DukoWiki __DokuWiki__ supports a simple markup language, which tries to make the //datafiles// to be as readable as possible. This page contains all possible **syntax** you may use when editing the pages. Simply have a look at the source of this page by pressing "__Edit this page__". If you want to try something, just use the **//playground//** page. The simpler markup is easily accessible via //quickbuttons//, too.

# What is a MD file MD files are basically **text files**. The text inside is written in one of many different dialects of the Markdown development language. They are used to author documentation also in a plain text format, so they can be turned into the //HTML format//. Furthermore, **MD files** are used to __version control source code __ because it makes it easy to compare the code to revisions that have been written in //**human-readable**// text. The data inside the **MD file** is saved in plain text. However, this text can contain __inline symbols__ that indicate how certain parts of the text should be formatted; such as\\ **bold**, __italic__, table formatting, and more. The developer of the MD file format, __John Gruber__, also developed\\ a program using the **Perl programming language** which allows the easy conversion of MD files in Markdown to HTML. Next to MD, //Markdown files// can also be saved using the **__MARKDOWN __** file extension.
