             <p>This tool attempts to detect <a href="//en.wikipedia.org/wiki/WP:COPYVIO">copyright violations</a> in articles. Simply give the title of the page you want to check and hit Submit. The tool will then search for its content elsewhere on the web and display a report if a similar webpage is found. If you also provide a URL, it will not query any search engines and instead display a report comparing the article to that particular webpage, like the <a href="//toolserver.org/~dcoetzee/duplicationdetector/">Duplication Detector</a>. Check out the <a href="//en.wikipedia.org/wiki/User:EarwigBot/Copyvios/FAQ">FAQ</a> for more information and technical details.</p>
+            <p><i>Note:</i> The tool is still in its earliest beta stages. You are completely welcome to use it and provide <a href="//en.wikipedia.org/wiki/User_talk:The_Earwig">feedback</a>, but be aware that it may produce strange or broken results.</p>
