为何Redis选择单线程而非多线程架构？

Links

Markdown supports two styles for Links:

• inline

  Syntax:
  [inline link text](www.inlinelink.com "optional title")

  Effect:
  inline link text

• reference

  Syntax:
  [reference link text][id]
[id]: www.referencelink.com "optional title"

  Effect:
  reference link text

Note:
The optional title is not necessary. You can input it for your demand.
Link definitions can be placed anywhere in your Markdown document.

Emphasis

Markdown uses asterisk(*) and underscore(_) symbol to wraps the text that you want to emphasis.

• Use one symbol asterisk* or underscore_ to wrap text, it will produce the < em> tag of HTML Tags.

  Syntax:
  *Sample Text* or _Sample Text_

  Effect:
  Sample Text or Sample Text

• Use double symbols asterisk* or underscore_, it will produce the < strong> tag of HTML Tags.

  Syntax:
  **Sample Text** or __Sample Text__

  Effect:
  Sample Text or Sample Text

Code

Markdown uses backtick quotes` to wrap the code text. It will produce the < code> tag of HTML tags.

Syntax:
`Code statement`

Effect:

And if you want to wrap the backtick quote` symbol. you can use double backticks as the opening and closing delimiter.

Syntax:
` ` There is a literal backtick(`) here ` `

Effect:

Image

Markdown uses an image syntax that is intended to resemble the syntax for links, allowing inline and reference

• inline

  Syntax:
  ![alt text](http://daringfireball.net/graphics/logos/ "optional title")

  Effect:
  

• reference

  Syntax:
  ![alt text][id]
[id]:http://daringfireball.net/graphics/logos/ "optional title"

Markdown has no syntax for specifying the dimensions of an image; if this is important to you, you can simply use regular HTML < img> tags.
