# Markdown: Syntax

Markdown is intended to be as easy-to-read and easy-to-write as is feasible.

Readability, however, is emphasized above all else. A Markdown-formatted
document should be publishable as-is, as plain text, without looking
like it's been marked up with tags or formatting instructions. While
Markdown's syntax has been influenced by several existing text-to-HTML
filters — including [Setext](http://docutils.sourceforge.net/mirror/setext.html), [atx](http://www.aaronsw.com/2002/atx/), [Textile](http://textism.com/tools/textile/), [reStructuredText](http://docutils.sourceforge.net/rst.html),
[Grutatext](http://www.triptico.com/software/grutatxt.html), and [EtText](http://ettext.taint.org/doc/) — the single biggest source of
inspiration for Markdown's syntax is the format of plain text email.

**Note:** This document is itself written using Markdown.

## Block Elements

### Paragraphs and Line Breaks

A paragraph is simply one or more consecutive lines of text, separated
by one or more blank lines. (A blank line is any line that looks like a
blank line — a line containing nothing but spaces or tabs is considered
blank.) Normal paragraphs should not be indented with spaces or tabs.

The implication of the "one or more consecutive lines of text" rule is
that Markdown supports "hard-wrapped" text paragraphs. This differs
significantly from most other text-to-HTML formatters (including Movable
Type's "Convert Line Breaks" option) which translate every line break
character in a paragraph into a `<br />` tag.

When you *do* want to insert a `<br />` break tag using Markdown, you
end a line with two or more spaces, then type return.

### Headers

Headers are lines that start with the `#` symbol.
The number of characters defines the header level,
from one (`#`) for `<h1>` to six (`######`) for `<h6>`.

### Blockquotes

Markdown uses email-style `>` characters for blockquoting. If you're
familiar with quoting passages of text in an email message, then you
know how to create a blockquote in Markdown. It looks best if you hard
wrap the text and put a `>` before every line:

> This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
> consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
> Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
>
> Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
> id sem consectetuer libero luctus adipiscing.

Markdown allows you to be lazy and only put the `>` before the first
line of a hard-wrapped paragraph:

> This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.

> Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
id sem consectetuer libero luctus adipiscing.

Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
adding additional levels of `>`:

> This is the first level of quoting.
>
> > This is nested blockquote.
>
> Back to the first level.

Blockquotes can contain other Markdown elements, including headers, lists,
and code blocks:

> ### Here's a list
>
> 1.   This is the first list item.
> 2.   This is the second list item.
>
> ### Here's an example code block
> ```
> const PI = 3.1415`
> ```

Any decent text editor should make email-style quoting easy. For
example, with BBEdit, you can make a selection and choose Increase
Quote Level from the Text menu.

### Lists

Markdown supports ordered (numbered) and unordered (bulleted) lists.

Unordered lists use asterisks, pluses, and hyphens — interchangably
— as list markers:

*   Red
*   Green
*   Blue

is equivalent to:

+   Red
+   Green
+   Blue

and:

-   Red
-   Green
-   Blue

Ordered lists use numbers followed by periods:

1.  Bird
2.  McHale
3.  Parish

It's important to note that the actual numbers you use to mark the
list have no effect on the HTML output Markdown produces. The HTML
Markdown produces from the above list is:

If you instead wrote the list in Markdown like this:

1.  Bird
1.  McHale
1.  Parish

or even:

3. Bird
1. McHale
8. Parish

you'd get the exact same HTML output. The point is, if you want to,
you can use ordinal numbers in your ordered Markdown lists, so that
the numbers in your source match the numbers in your published HTML.
But if you want to be lazy, you don't have to.

To make lists look nice, you can wrap items with hanging indents:

*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
    viverra nec, fringilla in, laoreet vitae, risus.
*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
    Suspendisse id sem consectetuer libero luctus adipiscing.

But if you want to be lazy, you don't have to:

*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
viverra nec, fringilla in, laoreet vitae, risus.
*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
Suspendisse id sem consectetuer libero luctus adipiscing.

List items may consist of multiple paragraphs. Each subsequent
paragraph in a list item must be indented by either 4 spaces
or one tab:

1.  This is a list item with two paragraphs. Lorem ipsum dolor
    sit amet, consectetuer adipiscing elit. Aliquam hendrerit
    mi posuere lectus.

    Vestibulum enim wisi, viverra nec, fringilla in, laoreet
    vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
    sit amet velit.

2.  Suspendisse id sem consectetuer libero luctus adipiscing.

It looks nice if you indent every line of the subsequent
paragraphs, but here again, Markdown will allow you to be
lazy:

*   This is a list item with two paragraphs.

    This is the second paragraph in the list item. You're
only required to indent the first line. Lorem ipsum dolor
sit amet, consectetuer adipiscing elit.

*   Another item in the same list.

To put a blockquote within a list item, the blockquote's `>`
delimiters need to be indented:

*   A list item with a blockquote:

    > This is a blockquote
    > inside a list item.

To put a code block within a list item, the code block needs
to be indented with list item indentation in mind:

*   A list item with a code block:

    ```
    code goes here
        code goes here
    ```

### Code Blocks

Pre-formatted code blocks are used for writing about programming or
markup source code. Rather than forming normal paragraphs, the lines
of a code block are interpreted literally. Markdown wraps a code block
in both `<pre>` and `<code>` tags.

```
tell application "Foo"
    beep
end tell
```

Regular Markdown syntax is not processed within code blocks. E.g.,
asterisks are just literal asterisks within a code block. This means
it's also easy to use Markdown to write about Markdown's own syntax.

```
## This is **not** a Markdown
```

### Tables

Markdown tables are created using pipes (|) to separate columns and hyphens (-) to define the header row. Here’s the basic structure:

1. Header Row: The first row contains column names.
2. Divider Line: The second row uses hyphens to separate the header from the data.
3. Data Rows: The rows below the divider contain the actual data.

| Name  | Age |  City    |
|-------|-----|-------|
| Alice | 25  | New York |
| Bob   | 30  | London   |

You can style text inside Markdown table cells just like regular Markdown.
This includes making text bold, italic, monospaced, or adding links or code.

Column 1 | Column 2 | Column 3
--- | --- | ---
**Things** | _Don't_ | [Need](/)
To | *__Look__* | `Pretty`

You can align text in Markdown table columns to the left, right, or center by placing a colon (:) in different positions within the header divider row.

1. Left-aligned: `:---` (Colon on the left)
2. Right-aligned: `---:` (Colon on the right)
3. Center-aligned: `:---:` (Colons on both sides)

| Column 1       | Column 2     | Column 3       |
| :------------- | :----------: | -----------:   |
|  Cell Contents | More Stuff   | And Again      |
| You Can Also   | Put Pipes In | Like this [\|] |

Markdown tables don’t support merging cells (like in HTML).
Each cell is treated separately.
But if you want an empty space, just leave it blank.

| Header 1 | Header 2 |
|----------|----------|
| Cell 1   |          |
| Cell 3   | Cell 4   |

## Span Elements

### Links

To create an inline link, use a set of regular parentheses immediately
after the link text's closing square bracket. Inside the parentheses,
put the URL where you want the link to point, along with an *optional*
title for the link, surrounded in quotes. For example:

This is [an example](http://example.com/) inline link.

[This link](/test/markdown/ "This is an example title") has a title attribute.

### Emphasis

Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
emphasis. Text wrapped with one `*` or `_` will be wrapped with an
HTML `<em>` tag; double `*`'s or `_`'s will be wrapped with an HTML
`<strong>` tag. E.g., this input:

*single asterisks*

_single underscores_

**double asterisks**

__double underscores__

### Code

To indicate a span of code, wrap it with backtick quotes (`` ` ``).
Unlike a pre-formatted code block, a code span indicates code within a
normal paragraph. For example:

Use the `printf()` function.
