This tag helper allows you to write Markdown directly in Razor and have that automatically converted to HTML at runtime. There are 2 options for how to use this tag helper. The first option is to use a <markdown> element.
<code><markdown>This is some _simple_ **markdown**.</markdown></code>
The tag helper will take this and convert it to the following HTML:
<p>This is some <em>simple</em><strong>markdown</strong>.</p>
The other option is to use a <p> element that has the markdown attribute:
<pmarkdown="">This is some _simple_ **markdown** in a _p_ element.</p>
