body: <p>I'm developing a mobile app that uses <a href="http://en.wiktionary.org/w/api.php" rel="noreferrer">Wiktionary API</a> for retrieving some articles from Wiktionary. This application is going to be commercial. I've read that Wiktionary materials are available under <a href="http://creativecommons.org/licenses/by-sa/3.0/" rel="noreferrer">Creative Commons Attribution-ShareAlike 3.0 Unported License</a>. Also I've read next statement in the Wiktionary Terms of Use:</p>
  
  <blockquote>
    <p>Please note that these licenses <strong>do allow commercial uses</strong> of your
    contributions, as long as such uses are compliant with the terms.</p>
  </blockquote>
  
  <p>So my question is: how exactly do I implement "CC BY-SA 3.0" license in my application? I mean: what (links, names or something else) and where (popups or menu items) should I put into my application to satisfy this license?</p>
