Here are a couple more examples of markdown elements. Here we have a blockquote:
The overriding design goal for Markdown's formatting syntax is to make it as readable as possible. The idea is that 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.
-- John Gruber
And a numbered list:
- Numbered Item 1
- Numbered Item 2
- Numbered Item 3
And a code block (with syntax highlighting).
title: Your Book Title Here
author:
name: Your Name Here
year: 2016
And a horizontal rule.
