## A first section ##

A simple list:

  1. Item 1
  2. Item 2

An unordered list:

  * First bullet
  * Second bullet

Now we have a blockquote:

> A big quote that goes on, and on, and on, and on, and on, and on, and on, and
> on
>
> A big quote that goes on, and on, and on, and on, and on, and on, and on, and

Some mathematics inline, $$X$$, a $100 million, a %tage and then a formula:

$$ \\sum_{i}^{\\infty} x^{n} + y^{n} = \\alpha +  \\beta * z^{n} $$

A paragraph with a[^fn1] footnote in it[^fn1].

[^fn1]: a very dull footnote indeed
       
       but it does have mutiple paragraphs.

A table now (this is *really* complicated):

<table class="data">
    <caption>My Caption</caption>
    <thead>
        <tr>
            <th>Heading 1</th><th>Heading 2</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>1.0%</td><td>2.0%</td>
        </tr>
        <tr>
            <td>1.0</td><td>2.0</td>
        </tr>
    </tbody>
</table>

Now let's try having an image:

<img src="blah.png" alt="abc abc" class="xyz" />

Stuff we should escape A&R, a %tage sign

    Now some preformatted text:
    
      $ sudo python ...
