github.com advanced markdown inside blockquote
<p>I'm writing a <code>README.md</code> for one of my repositories on <a href="http://github.com" rel="nofollow"><code>github.com</code></a>.<br>
As part of this <code>README.md</code> I'd like to include a quote of another <code>README.md</code> (from another repository), which implies using advanced markdown inside the quote.  </p>

<p>Eventually I'd like to see something like this:  </p>

<hr>

<ul>
<li>Item 1

<ul>
<li>Use the following:

<blockquote>
  <ul>
  <li>First level of quoted list
  
  <ul>
  <li>Second level of quoted <strong><em>list</em></strong></li>
  <li><blockquote>
    <p>Nested <em>quote</em></p>
  </blockquote></li>
  </ul></li>
  </ul>
</blockquote></li>
</ul></li>
<li>Item 2</li>
</ul>

<hr>

<p>For now I'm trying to achieve this with the following markdown:  </p>

<pre><code> * Item 1
    * Use the following   
        &gt; * First level of quoted list
        &gt;   *  Second level of quoted ***list***  
        &gt;   * &gt; Nested *quote*
 * Item 2
</code></pre>

<p>There are several online markdown editors out there that intend to simulate <code>github</code> markdown behavior: <a href="https://jbt.github.io/markdown-editor/#Zc4xDoJAEIXhej3FX08nB6A0sbExnkAG3WRkojvC9VnAhMLqFf9XPIRz6IvjgSTcihJPpXczn/LwAGpILcIpf0pgOqrhPe+vh3ZYLrEJquGqdx+6PyUiC6yz25aLljWuqJbflWYG" rel="nofollow">ones</a> that work much better than <code>github</code> itself, <a href="http://dillinger.io/" rel="nofollow">others</a> that are a bit more realistic, but in <code>github</code> it looks like this:</p>

<hr>

<ul>
<li>Item 1  

<ul>
<li>Use the following<br>
> * First level of quoted list > * Second level of quoted list > * > Nested quote  </li>
</ul></li>
<li>Item 2</li>
</ul>

<hr>

<p>So it appears that <code>github</code> supports some simple markdown inside the block quote (like bold, italic etc.), but it won't support the advanced markdown (like lists, quotes etc.)  </p>

<p>Is there any way to quote a complex markdown on <code>github</code>?</p>
