title: Change Default settings in Sublime Text 3
body: <p>After installing sublime text 3 on Linux, I cannot seem to change the default settings, for example:</p>
  
  <pre><code> // Controls auto pairing of quotes, brackets etc
  "auto_match_enabled": true,
  </code></pre>
  
  <p>I can't replace true to false. The file appears to be read-only.</p>
