 <h3>About Autocrypt</h3>
 <p>
-  Autocrypt replaces the use of cleartext with
-  end-to-end encrypted e-mail. We encourage
-  adoption by radically simplifying user experience 
-  and by using in-band opportunistic key discovery.
-  See <a href="https://github.com/autocrypt/autocrypt/">autocrypt/autocrypt
-  github repo</a> for the source.
+  Autocrypt aims to automatically replace the use of 
+  cleartext with end-to-end encrypted e-mail.
