Alternately, you can use this tool to generate one:

A readme.txt is needed so your plugin will display correctly in our repository, but also so we can make sure you're providing the users with all the information they need before they install your plugin. Our goal with this is to make sure everyone knows what they're installing and what they need to do before they install it. No surprises :)

This is especially important if your plugin is making calls back to your own servers. For the most part, we do not permit offloading of images or code, however in the case where you are providing a service (like Disqus or Akismet or Twitter), we permit it. The catch is you have to actually explain this to the layman in your readme, so they know where data is going.

Also this code is problematic:

print '<div style="margin-top:10px;">Visual QR Code by Visualead.com</div>
</div><script type="text/javascript" src="http://vqrs.visualead.com/wordpress-widget/js/visualead_wordpress.js"></script>';

You're calling external JS AND you're putting in credit links. We don't permit either of that.

Please send a link so the completed plugin can be downloaded. Alternately you can reply to this and send a .zip or .rar file. As this is for a new plugin request, please reply within seven days of this email or we will reject your plugin.
