Sometimes you want numbered lists:

1. One
2. Two
3. Three

Sometimes you want bullet points:

• Start a line with a star
• Profit!

Alternatively,

• Dashes work just as well
• And if you have sub points, put two spaces before the dash or star:
  • Like this
  • And this

If you want to embed images, this is how you do it:

Structured documents

Sometimes it’s useful to have different levels of headings to structure your documents. Start lines with a # to create headings. Multiple ## in a row denote smaller heading sizes.

This is a third-tier heading

You can use one # all the way up to ###### six for different heading sizes.

If you’d like to quote someone, use the > character before the line:

There are many different ways to style code with GitHub’s markdown. If you have inline code blocks, wrap them in backticks: var example = true. If you’ve got a longer block of code, you can indent with four spaces:

if (isAwesome){
    return true
    }

GitHub also supports something called code fencing, which allows for multiple lines without indentation:

if (isAwesome){
    return true
    }

And if you’d like to use syntax highlighting, include the language:

if (isAwesome){
  return true
}

	public static void main(String[] args)
	{
	System.out.println("Hello World");
	}
	

GitHub supports many extras in Markdown that help you reference and link to people. If you ever want to direct a comment at someone, you can prefix their name with an @ symbol: Hey @kneath — love your sweater!

But I have to admit, tasks lists are my favorite:

• This is a complete item
• This is an incomplete item

And, of course emoji!
