title: Edit a Hash contained in another Hash
body: <p>I have a Hash inside a Hash with the following structure:</p>
  
  <pre><code>mysystem = {
    "slicompany" =&gt; {
      "sahil" =&gt; "developer",
      "Jag" =&gt; "developer"
    },
    "uzanto" =&gt; {
      "kapil" =&gt; "tech lead"
    }
  }
  </code></pre>
  
  <p>What is the best way to add/delete/edit the elements of the inner Hashes?</p>
