# What is Markdown?

Markdown is a lightweight markup language, designed to be easy to write and easy to read.
It provides formatting for things like headings, emphasis, blockquotes and lists.

## Example Markdown

Let’s create a bit of markdown and show how it’s displayed. Headers, for example, are simple text strings that sit on a line by themselves, with one or more # characters in the first position:

Here’s what that code looks like when rendered:

Some more stuff under that heading.

Let’s mix things up by adding in a list:

1. Item One
2. Item Two
3. Item Three

GitHub, in fact, defaults to creating and displaying a file called README.md in their repositories.
