Markdown: Reference to section from another file : <p>I have two markdown files: a <code>parent.md</code> and a <code>child.md</code>.</p>

<p>So <code>parent.md</code>:</p>

<pre><code># Main section

## sub-section
</code></pre>

<p>I'd like to make reference to <code>## sub-section</code> from <code>child.md</code>.</p>

<p>Any ideas?</p>
