Formatting demonstration

This page demonstrates formatting.

Two new lines to make one new line

Or you can do line break command and keep typing?

What about with a single break?

Then it looks like this

external link single brackets external link

internal link double brackets Main Page

Level 2 header, has an underline
stuff

Level 2 header, has an underline
things

Level 2 header, if you have enough headers, it automatically makes a contents
but it is above first header

Level 3 header

 * Asterisks
 * Make indentation
 * Not sure what I want to use as standard

Escaped less than &lt; and escaped greater than &gt;

But less and greater in isolation don't do anything, like. In import they are bad however and need to be escaped

What about single brackets no link format? Only if full http // indicator [http:/two words]

look a category tag

but it shows up at the bottom, no matter what

Characters that are ok at least in isolation < > ! @ # $ % ^ & * - _ / | \ ? ., ` ~ ' " = +
