# About > Markdown is a lightweight markup language with plain text formatting syntax. - *[Daring Fireball](https://daringfireball.net/projects/markdown/)* This is an example [markdown](https://daringfireball.net/projects/markdown/syntax) page. You can [view the raw file](https://raw.githubusercontent.com/cpl-makerlab/markdown-example/master/README.md) or edit this file directly in Github's built-in editor or your own code editor. Github automatically renders markdown files when viewing. Here's the [official markdown documentation](https://daringfireball.net/projects/markdown/), and [github-flavored markdown's documentation](https://guides.github.com/features/mastering-markdown/) (some slight differences). Usually HTML is allowed within Markdown, but on Github only certain tags are allowed. Markdown syntax supports [hyperlinks](http://www.duckduckgo.com), *italics*, **bold** text, and lots more. # Heading 1 ## Heading 2 ### Heading 3 #### Heading 4 #### Unordered List - apples - oranges - bananas #### Ordered list 1. drums 2. bass 3. guitar > Blockquote (highlighted text) ![Angry Ostrich](https://i.imgur.com/lF5woJMl.jpg) Column1 | Column2 | Column3 --- | --- | --- What | about | tables?

Three asterisks creates a horizontal line. *** Standard HTML formatting is also allowed within Markdown. Github-flavored Markdown does not support all HTML tags, however (i.e. iframe and script tags).
