Markdown 的目標是實現「易讀易寫」。

不過最需要強調的便是它的可讀性。一份使用 Markdown 格式撰寫的文件應該可以直接以純文字發佈，並且看起來不會像是由許多標籤或是格式指令所構成。

因此 Markdown 的語法全由標點符號所組成，並經過嚴謹慎選，是為了讓它們看起來就像所要表達的意思。像是在文字兩旁加上星號，看起來就像*強調*。Markdown 的清單看起來，嗯，就是清單。假如你有使用過電子郵件，區塊引言看起來就真的像是引用一段文字。

Code blocks use the peppermint theme.

class Awesome < ActiveRecord::Base
  include EvenMoreAwesome

  validates_presence_of :something
  validates :email, email_format: true

  def initialize(email, name = nil)
    self.email = email
    self.name = name
  end
end
<!DOCTYPE html>

<style>body {width: 500px;}</style>

They draw the perfect amount of attention

This allows your content to have the proper informational and contextual hierarchy. Yay.

The default math delimiters are $$. Hence $$ E = m \cdot c^2 $$ yields \(E = m \cdot c^2\)

And here’s something more fancy:

\[\zeta(s) = \frac{1}{\Gamma(s)} \int \limits_0^\infty x^{s-1} \sum_{n=1}^\infty e^{-nx} \mathrm{d}x = \frac{1}{\Gamma(s)} \int \limits_0^\infty \frac{x^{s-1}}{e^x - 1} \mathrm{d}x\]

There’s more being added all the time
