Markdown Parser
Markdown is a quick and easy way to create web pages using a small number of editing symbols.

Headings
For example, the # symbol is used to indicate a heading:
#Largest Heading
##Second Largest Heading
###Third Largest Heading
####Fourth Largest Heading
#####Small Heading
HTML:
Largest Heading
Second Largest Heading
Third Largest Heading
Fourth Largest Heading
Small Heading
Bullet List
To create a bullet list, use * before each item. Be sure to include a space between the * and the text.
* This is item 1
* This is item 2
* This is item 3
HTML:
- This is item 1
- This is item 2
- This is item 3
Bold
You can make a text item bold by enclosing it in ** ;
**This is bold text**
HTML:
This is bold text
Italics
You can make a text item italic by enclosing it in a single *.
*This is italic text*
HTML:
This is italic text
Block Quotes
Start paragraph with >
A double space ends the quotation
>This is a quote
And this is a second line of the quote
HTML:
This is a quote
And this is the second line of the quote
Links
The text for the link goes inside square brackets, and the url goes inside parenthesis:
[Amazing Animals](https://wealthycats.com)
Amazing Animals
HTML:
Pictures
Pictures are almost the same as links, but there is a ‘!” in front of the square brackets:
HTML:
Picture LInks
Picture links are a combination of the markdown for pictures and links:
[](https://wealthycats)
This is a picture:
