title: Markdown: Links to markdown files in nested directories
body: <p>I created a Bitbucket wiki.</p>
  
  <p>And I find an issue: how to make links to pages in nested folders?</p>
  
  <p>I have a structure:</p>
  
  <ul>
  <li><code>one.md</code></li>
  <li><code>two.md</code></li>
  <li><code>dir1/</code>
  <ul>
  <li><code>three.md</code></li>
  </ul></li>
  <li><code>dir2/</code>
  <ul>
  <li><code>four.md</code></li>
  </ul></li>
  </ul>
  
  <p>If I want to add on home wiki pages one or two, I will use</p>
  
  <pre><code>[[one]]  
  [[two]]
  </code></pre>
  
  <p>But if I write something similar for other pages...</p>
  
  <pre><code>[[dir1/three]]  
  [[dir2/four]]
  </code></pre>
  
  <p>nothing seems to be ok.</p>
  
  <p>What is the correct symbol that separate folders in path to file?</p>
  
  <p>What is the correct way for nested directories in markdown wiki?</p>
