Markdown

Markdown is an easy-to-read, easy-to-write syntax for formatting plain text.

Headers

# h1 Heading
## h2 Heading
### h3 Heading
#### h4 Heading
##### h5 Heading
###### h6 Heading

Alternatively, for H1 and H2, an underline-ish style:

Alt-H1
======

Alt-H2
------


h1 Heading

h2 Heading

h3 Heading

h4 Heading

h5 Heading
h6 Heading

Emphasis

Emphasis, aka italics, with *asterisks* or _underscores_.

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

Combined emphasis with **asterisks and _underscores_**.

Strikethrough uses two tildes. ~~Scratch this.~~

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

1. First ordered list item

2. Another item

• Unordered sub-list.
3. Actual numbers don't matter, just that it's a number

Links

There are two ways to create links.

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

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

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

[I'm a relative reference to a repository file](../blob/master/LICENSE)

[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> and sometimes
example.com (but not on Github, for example).

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

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

Code and Syntax Highlighting

Code blocks are part of the Markdown spec, but syntax highlighting isn't. However, DocsApp.io support highlighting for dozens of languages (and not-really-languages, like diffs and HTTP headers).

Inline code has back-ticks around it.


Inline code has back-ticks around it.

Blocks of code are either fenced by lines with three back-ticks , or are indented with four spaces. I recommend only using the fenced code blocks -- they're easier and only they support syntax highlighting.

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

Tables aren't part of the core Markdown spec, but they are part of GFM and DocsApp.io supports them. They are an easy way of adding tables to your email -- a task that would otherwise require copy-pasting from another application.

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  Colons can be used to align columns. Tables Are Cool col 3 is right-aligned1600

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.

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

You can also use raw HTML in your Markdown, and it'll 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>


Horizontal Rule

Three or more...

Line Breaks

My basic recommendation for learning how line breaks work is to experiment and discover -- hit once (i.e., insert one newline), then hit it twice (i.e., insert two newlines), see what happens. You'll soon learn to get what you want. "Markdown Toggle" is your friend.

Here are some things to try out:

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*.
