Here's some of the syntax supported

Paragraphs

Paragraphs in Markdown are just one or more lines of consecutive text followed by one or more blank lines.

On July 2, an alien mothership entered Earth's orbit and deployed several dozen saucer-shaped "destroyer" spacecraft, each 15 miles (24 km) wide.

On July 3, the Black Knights, a squadron of Marine Corps F/A-18 Hornets, participated in an assault on a destroyer near the city of Los Angeles.

Headings

You can create a heading by adding one or more # symbols before your heading text. The number of # you use will determine the size of the heading. This is similar to atx style.

# The largest heading (an <h1> tag)
## The second largest heading (an <h2> tag)
…
###### The 6th largest heading (an <h6> tag)

You can also use setext style headings.

This is an H1
=============

This is an H2
-------------

Blockquotes

You can indicate blockquotes with a >.

In the words of Abraham Lincoln:

> Pardon my french

Styling text

You can make text bold or italic.

*This text will be italic*
**This text will be bold**

Both bold and italic can use either a * or an _ around the text for styling. This allows you to combine both bold and italic if needed.

**Everyone _must_ attend the meeting at 5 o'clock today.**

Lists

Unordered lists

You can make an unordered list by preceding list items with either a * or a -.

* Item
* Item
* Item

- Item
- Item
- Item

Ordered lists

You can make an ordered list by preceding list items with a number.

1. Item 1
2. Item 2
3. Item 3

Nested lists

You can create nested lists by indenting list items by two spaces.

1. Item 1
  1. A corollary to the above item.
  2. Yet another point to consider.
2. Item 2
  * A corollary that does not need to be ordered.
  * This is indented four spaces, because it's two spaces further than the item above.
  * You might want to consider making a new list.
3. Item 3

Code formatting

Inline formats

Use single backticks (`) to format text in a special monospace format. Everything within the backticks appear as-is, with no other special formatting.

Here's an idea: why don't we take `SuperiorProject` and turn it into `**Reasonable**Project`.

Multiple lines

Showdown wraps a code block in both <pre> and <code> tags.

To produce a code block in Markdown, simply indent every line of the block by at least 4 spaces or 1 tab.

This is a normal paragraph:

    This is a code block.

You can also use triple backticks to format text as its own distinct block.

Check out this neat program I wrote:

```
x = 0
x = 2 + 2
what is x
```

Links

Showdown supports two style of links: inline and reference.

Inline

You can create an inline link by wrapping link text in brackets ( [ ] ), and then wrapping the link in parentheses ( ( ) ).

For example, to create a hyperlink to showdown.github.io, with a link text that says, Showdown is great!, you'd write this in Markdown:

[Showdown is great!](http://showdown.github.io/)

Reference

Reference-style links use a second set of square brackets, inside which you place a label of your choosing to identify the link:

This is [an example][id] reference-style link.

Then, anywhere in the document (usually at the end), you define your link label like this, on a line by itself:

[id]: http://example.com/  "Optional Title Here"

Tables

Tables aren't part of the core Markdown spec, but they are part of GFM and Showdown supports them by turning on the flag tables.

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

this will produce this:

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

Colons can be used to align columns.

The outer pipes (|) are NOT optional. But you don't need to make the raw Markdown line up prettily.

You can also use other markdown syntax inside them.
