Emphasis, aka italics, with asterisks or underscores.

Strong emphasis, aka bold, with asterisks or underscores.

Combined emphasis with asterisks and underscores.

Strikethrough uses two tildes. Scratch this.

목록

1. First ordered list item
2. Another item
   • Unordered sub-list.
3. Actual numbers don't matter, just that it's a number
   1. Ordered sub-list
4. And another item.

Some text that should be aligned with the above item.

• Unordered list can use asterisks
• Or minuses
• Or pluses

링크
I'm an inline-style link

I'm a reference-style link

You can use numbers for reference-style link definitions

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.

코드
Code blocks are part of the Markdown spec, but syntax highlighting isn't. However, many renderers -- like Github's and Markdown Here -- support syntax highlighting. Markdown Here supports highlighting for dozens of languages (and not-really-languages, like diffs and HTTP headers); to see the complete list, and how to write the language names, see the highlight.js demo page.

Inline code has back-ticks around it.
Inline code has back-ticks around it.

Blocks of code are either fenced by lines with three back-ticks

```, or are indented with four spaces. I recommend only using the fenced code blocks -- they're easier and only they support syntax highlighting.

javascript
var s = "JavaScript syntax highlighting";
alert(s);

python
s = "Python syntax highlighting"
print s

No language indicated, so no syntax highlighting. 
But let's throw in a <b>tag</b>.

테이블
Colons can be used to align columns.

Tables	Are	Cool
col 3 is	right-aligned	$1600
col 2 is	centered	$12
zebra stripes	are neat	$1

The outer pipes (|) are optional, and you don't need to make the raw Markdown line up prettily. You can also use inline Markdown.

Markdown	Less	Pretty
Still	renders	nicely
1	2	3

인용

Blockquotes are very handy in email to emulate reply text.
This line is part of the same quote.

Quote break.

This is a very long line that will still be quoted properly when it wraps. Oh boy let's keep writing to make sure this is long enough to actually wrap for everyone. Oh, you can put Markdown into a blockquote.

Is something people use sometimes.

Does *not* work **very** well. Use HTML tags.

Here's a line for us to start with.

This line is separated from the one above by two newlines, so it will be a separate paragraph.

This line is also a separate paragraph, but...
This line is only separated by a single newline, so it's a separate line in the same paragraph.
