markdown file code example

Example 1: markdown link

[I'm an inline-style link](https://www.google.com)

[I'm an inline-style link with title](https://www.google.com "Google's Homepage")

[I'm a reference-style link][Arbitrary case-insensitive reference text]

[I'm a relative reference to a repository file](../blob/master/LICENSE)

[You can use numbers for reference-style link definitions][1]

Or leave it empty and use the [link text itself].

URLs and URLs in angle brackets will automatically get turned into links. 
http://www.example.com or <http://www.example.com> and sometimes 
example.com (but not on Github, for example).

Some text to show that the reference links can follow later.

[arbitrary case-insensitive reference text]: https://www.mozilla.org
[1]: http://slashdot.org
[link text itself]: http://www.reddit.com

Example 2: what is a markdown .md file

A file with the .MD or .MARKDOWN file extension might be a Markdown Documentation file. It's a plain text file that uses the Markdown language to describe how to convert a text document to HTML. README.md is a common MD file that holds text instructions.

Example 3: markdown

Markdown is a lightweight markup language with plain-text-formatting syntax,
created in 2004 by John Gruber and Aaron Swartz.
Markdown is often used for formatting readme files,
for writing messages in online discussion forums, 
and to create rich text using a plain text editor.
