A list with numbers: 1. One 2. Two 3. Three

A list with bullets: Bullet Bullet * Bullet

Here's a blockquote:

Simple is better than complex

Here's a table:

Column1	Column 2	Column 3
Value 1	Value 2	Value 3
Value 4	Value 5	Value 6
Value 7	Value 8	Value 9

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

There must be at least 3 dashes separating each header cell. 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
