An exhibit of Markdown
This note demonstrates some of what [Markdown][1] is capable of doing.
Note: Feel free to play with this page. Unlike regular notes, this doesn&apost automatically save itself.
Basic formatting
Paragraphs can be written like so. A paragraph is the basic block of Markdown. A paragraph is what text will turn into when there is no reason it should become anything else.
Paragraphs must be separated by a blank line. Basic formatting of italics and bold is supported. This can be nested like so.
Lists
Ordered list
* Item 1
* A second item
* Number 3
* Ⅳ
Note: the fourth item uses the Unicode character for [Roman numeral four][2].
Unordered list
* An item
* Another item
* Yet another item
* And there&aposs more…
Paragraph modifiers
Code block
Code blocks are very useful for developers and other people who look at code or other things that are written in plain text. As you can see, it uses a fixed-width font.
You can also make inline code to add code into other things.
Quote
Here is a quote. What this is should be self explanatory. Quotes are automatically indented when they are used.
Headings
There are six levels of headings. They correspond with the six levels of HTML headings. You&aposve probably noticed them already in the page. Each level down uses one more hash character.
Headings can also contain formatting https://goo.gl/gaZ5ja #BigData #Analytics
