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.


  1. First ordered list item
  2. Another item
    Some text that should be aligned with the above item.

There are two ways to create links.
I’m an inline-style link

I’m a reference-style link

I’m a relative reference to a repository file

You can use numbers for reference-style link definitions

Or leave it empty and use the link text itself

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

Code and Syntax Highlighting

Code blocks are part of the Markdown spec, but syntax highlighting isn’t. However, many renderers – like Github’s and Markdown Here – support syntax highlighting. Markdown Here supports highlighting for dozens of languages (and not-really-languages, like diffs and HTTP headers); to see the complete list, and how to write the language names, see the highlight.js demo page.

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.

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

(Github Wiki pages don’t seem to support syntax highlighting, so the above won’t be colourful (the strings are not red, for example). Try it out in a Markdown Here email or a Github Markdown README or Github Issue – you can preview a new Issue without submitting it.)

Again, to see what languages are available for highlighting, and how to write those language names, see the highlight.js demo page.


Tables aren’t part of the core Markdown spec, but they are part of GFM and Markdown Here 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

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

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.

Inline HTML

You can also use raw HTML in your Markdown, and it’ll mostly work pretty well.

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

Line Breaks

My basic recommendation for learning how line breaks work is to experiment and discover – hit <Enter> 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 begins a separate paragraph, but…
This line is only separated by a single newline, so it’s a separate line in the same paragraph.

(Technical note: Markdown Here uses GFM line breaks, so there’s no need to use MD’s two-space line breaks.)

Youtube videos

They can’t be added directly but you can add an image with a link to the video like this:

Or, in pure Markdown, but losing the image sizing and border:
