Philosophy

Markdown is intended to be as easy-to-read and easy-to-write as is feasible.
Readability, however, is emphasized above all else. A Markdown-formatted document should be publishable as-is, as plain text, without looking like it's been marked up with tags or formatting instructions.
Markdown's syntax is intended for one purpose: to be used as a format for writing for the web.

Notice

You can use CMD + 4 or CMD + R to preview the result.

As Kanye West said:
> We're living the future so
> the present is our past.

Shortcuts: CMD + Shift + B
Result:

As Kanye West said:

the present is our past.

Inline code

Example:

I think you should use an
`<addr>` `code` element here instead.

Shortcuts: CMD + K
Result:

I think you should use an
<addr> code element here instead.

Multi-line code

Example:

```js
function fancyAlert(arg) {
  if(arg) {
    $.facebox({div:'#foo'})
  }

}
```

Shortcuts: CMD + Shift + K
Result:

function fancyAlert(arg) {
  if(arg) {
    $.facebox({div:'#foo'})
  }

}

Sequence and Flow chart

Example:

```sequence
Andrew->China: Says Hello
Note right of China: China thinks about it
China-->Andrew: How are you?
Andrew->>China: I am good thanks!
```

```flow
st=>start: Start:>http://www.google.com[blank]
e=>end:>http://www.google.com
op1=>operation: My Operation
sub1=>subroutine: My Subroutine
cond=>condition: Yes
or No?:>http://www.google.com
io=>inputoutput: catch something...

st->op1->cond
cond(yes)->io->e
cond(no)->sub1(right)->op1
```

Result: ( Please enable Preferences - Themes - Enable sequence & flow chart, default is enable. )

Andrew->China: Says Hello
Note right of China: China thinks about it
China-->Andrew: How are you?
Andrew->>China: I am good thanks!

st=>start: Start:>http://www.google.com[blank]
e=>end:>http://www.google.com
op1=>operation: My Operation
sub1=>subroutine: My Subroutine
cond=>condition: Yes
or No?:>http://www.google.com
io=>inputoutput: catch something...
    
st->op1->cond
cond(yes)->io->e
cond(no)->sub1(right)->op1

Tables

Example:

First Header | Second Header
------------ | -------------
Content from cell 1 | Content from cell 2
Content in the first column | Content in the second column

You can create tables by assembling a list of words and dividing them with hyphens - (for the first row), and then separating each column with a pipe |:

Result:

First Header	Second Header
Content from cell 1	Content from cell 2
Content in the first column	Content in the second column

Strikethrough

Example:

 (like ~~this~~)

Result:

Any word wrapped with two tildes (like this) will appear crossed out.

Horizontal Rules

Following lines will produce a horizontal rule:

***

*****

- - -

Result:

---

MathJax

Use double US dollors sign pair for Block level Math formula, and one US dollor sign pair for Inline Level.

For example this is a Block level $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$ formula, and this is an inline Level $x = {-b \pm \sqrt{b^2-4ac} \over 2a}$ formula.

\\[ \frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} =
1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}}
{1+\frac{e^{-8\pi}} {1+\ldots} } } } \\]

Result:

For example this is a Block level \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) formula, and this is an inline Level \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) formula.

\[ \frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} =
1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}}
{1+\frac{e^{-8\pi}} {1+\ldots} } } } \]

Footnote

Example:

This is a footnote:[^sample_footnote]

Result:

This is a footnote:¹
