1. First ordered list item

  1. Ordered sub-list
4. And another item.

   You can have properly indented paragraphs within list items. Notice the blank line above, and the leading spaces (at least one, but we'll use three here to also align the raw Markdown).

   To have a line break without a paragraph, you will need to use two trailing spaces.  
   Note that this line is separate, but within the same paragraph.  
   (This is contrary to the typical GFM line break behaviour, where trailing spaces are not required.)

* Unordered list can use asterisks
- Or minuses
+ Or pluses
- Paragraph In unordered list

  For example like this.

Common Paragraph with some text.
And more text.

Code and Syntax Highlighting

Inline code has back-ticks around it.

alert(s);

s = "Python syntax highlighting"
print s

No language indicated, so no syntax highlighting.

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.

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*.
