.md file format code example
Example 1: markdown link syntax
[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: .md file?
An MD file is a text file created using one of several possible
dialects of the Markdown language. It is saved in plain text format
but includes inline symbols that define how to format the text
(e.g. bold, indentations, headers, table formatting)
Example 4: md format

Example 5: md format
I think you should use an
`<addr>` element here instead.
