#sample Markdown content refData ------------------------------------.

H2

H3

H4

H5

H6

Alternatively, for H1 and H2, an underline-ish style:

Alt-H2

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.

Lists

1. First ordered list item
2. Another item

• Unordered sub-list.

1. Actual numbers don't matter, just that it's a number

2. Ordered sub-list

3. And another item.

   Some text that should be aligned with the above item.

• Unordered list can use asterisks

• Or minuses

• Or pluses

Links - two styles

I'm an inline-style link (opens in a new tab)

I'm a reference-style link (opens in a new tab)

You can use numbers for reference-style link definitions (opens in a new tab)

Or leave it empty and use the link text itself (opens in a new tab)

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

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

Images

Here's our logo (hover to see the title text):

Reference-style:

Code - Inline

Inline code has back-ticks around it.

Code-blocks

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

s = "Python syntax highlighting"
print s

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

Tables

Colons can be used to align columns.

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

BlockQuotes

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

Inline HTML

Definition list

Is something people use sometimes.

Markdown in HTML

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

HR: The Horizontal rule

Three or more...

Hyphens

Asterisks

Underscores

Linebreaks and Paragraphs

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.

TeX Maths formulae

$ax^2 + bx + c$ $-b \pm \sqrt{b^2 - 4ac} \over 2a$ $x = a_0 + \frac{1}{a_1 + \frac{1}{a_2 + \frac{1}{a_3 + a_4}}}$ $\forall x \in X, \quad \exists y \leq \epsilon$

The beginning and ending dollar marks $ are TeX markup indicators
