Horizontal Rule

You can produce a horizontal rule tag by placing three or more hyphens, asterisks, or underscores on a line by themselves.

Headers

Markdown supports two styles of headers, Setext and atx.

Setext-style headers are “underlined” using equal signs (for first-level headers) and dashes (for second-level headers).
For example:

This is an H1

This is an H2

Atx-style headers use 1-6 hash characters at the start of the line, corresponding to header levels 1-6.
For example:

This is an H1

This is an H2

This is an H3

This is an H4

This is an H5

This is an H6

Text

###Highlighting

`Linux` `Github`

Effect: Linux Github

Line Breaks

Can't newline directly, you can fill two spaces in the back on a line of text, so the next line of text will be a new line.
For example:

Live well, love lots, and laugh often.  
Keep trying no matter how hard it seems, it will get easier.

Live well, love lots, and laugh often.
Keep trying no matter how hard it seems, it will get easier.

Images

Image syntax looks like this:

![Alt text](/path/to/img.jpg "Optional title")

• An exclamation mark: !
• Alt: text for the image
• The URL or path of the image
• An optional title attribute enclosed in double or single quotes.

For example:

![github-logo](https://github.com/alandtsang/README/blob/master/images/github-logo.png "Optional title")

Links

###Links to external URL

Syntax	Effect
[My Github][alandtsang Github]	My Github
[alandtsang Github]:https://github.com/alandtsang

The first bracket is a identifier, and the second bracket is actual URL. [identifier][URL]

###Link to the URL in this repository

Syntax	Effect
[images](/images)	images

Lists

Markdown supports ordered (numbered) and unordered (bulleted) lists.

Unordered lists use asterisks, pluses, and hyphens — interchangably — as list markers:

* Red
* Green
* Blue

is equivalent to:

+ Red
+ Green
+ Blue

and:

- Red
- Green
- Blue

Ordered lists use numbers followed by periods:

1. Elephant
2. Tiger
3. Monkey

Code Highlighting

Behind three backquotes is the name of the programming language.
For example:

int main(int argc, char **argv)	//C

if __name__ == '__main__':	//python
    function()

Form

Header1	Header2
Cell1	Cell2
Cell3	Cell4
