Emphasis

Strong emphasis, aka bold, with **asterisks** or __underscores__.

Combined emphasis with **asterisks and _underscores_**.

Lists

(In this example, leading and trailing spaces are shown with with dots: ⋅)

1. First ordered list item
2. Another item
⋅⋅* Unordered sub-list. 
1. Actual numbers don't matter, just that it's a number
⋅⋅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

Links

Links can be created at the same place where they are referenced using parenthesis.

[I'm an inline-style link](https://www.duckduckgo.com)

[I'm an inline-style link with title](https://www.duckduckgo.com "Duck Duck Go's Homepage")

I’m an inline-style link

I’m an inline-style link with title

Or links can be put in other places, like at the end of the chapter or the page, if using squared brackets.

[I'm a reference-style link][Arbitrary case-insensitive reference text]

[You can use numbers for reference-style link definitions][1]

Or leave it empty and use the [link text itself].

URLs and URLs in angle brackets will automatically get turned into links. http://www.example.com or <http://www.example.com>.

Some text to show that the reference links can follow later.

[arbitrary case-insensitive reference text]: https://www.mozilla.org
[1]: https://www.mozilla.org
[link text itself]: https://www.mozilla.org

I’m a reference-style link

You can use numbers for reference-style link definitions

Or leave it empty and use the link text itself.

URLs and URLs in angle brackets will automatically get turned into links. http://www.example.com or http://www.example.com.

Some text to show that the reference links can follow later.

Images

Upload images the same way as markdown files. Reference them directly.

Supawiki logo:

![supawiki][logo]

[logo]: (image-name) "Supawiki logo"

Where “(image-name)” is the name and extension of the image file (do not include the parenthesis).

Add subtitles using HTML directly:

![supawiki][logo]
<small>Supawiki logo. Source: <a target='_blank' rel='noopener noreferrer' href='https://www.supawiki.com'>Supawiki</a></small>

Supawiki logo. Source: Supawiki

Code and syntax highlighting

Code blocks are part of the Markdown spec, and Supawiki adds support for code highlighting.

Inline `code` has `back-ticks around` it.

Inline code has back-ticks around it.

Blocks of code are fenced by three back ticks (```).

```javascript
var s = "JavaScript syntax highlighting"
alert(s)
```

```python
s = "Python syntax highlighting"
print s
```

```
No language indicated, so no syntax highlighting.
But let's throw in a tag.
```

var s = "JavaScript syntax highlighting"
alert(s)

s = "Python syntax highlighting"
print s

No language indicated, so no syntax highlighting. 
But let's throw in a <b>tag</b>.

Tables

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**
1 | 2 | 3

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.

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.

Inline HTML

Raw HTML can be used in Markdown, and it will mostly work pretty well.

<dl>
  <dt>Definition list</dt>
  <dd>Is something people use sometimes.</dd>

  <dt>Markdown in HTML</dt>
  <dd>Does *not* work **very** well. Use HTML <em>tags</em>.</dd>
</dl>

Definition list: Is something people use sometimes.
Markdown in HTML: Does *not* work **very** well. Use HTML tags.
