 ##What does Clipperz do?
 
 Clipperz is an online vault where you can store confidential data without worrying about security. It can be used to save and manage passwords, private notes, burglar alarm codes, credit and debit card details, PINs, software keys, …
 Since passwords are the most common type of private information that you need to protect, we have added a great deal of functionality to make Clipperz a great [online password manager][home] thus solving the “password fatigue” problem.
 
 **Clipperz makes the Internet the most convenient and safe place to keep you most precious and sensitive data.**

-[contact]: http://www.clipperz.com/about/contacts
+The open source version of Clipperz is suitable for **testing and educational purposes only**. Do not use it as an actual password management solution.
+
+As an example, the current PHP backend lacks several critical capabilities such as bot protection and concurrent sessions management, moreover it could be vulnerable to serious threats (SQL injections, remote code execution, ...).

   The application needs a simple MySQL database; to configure all the credentials to access the previously allocated DB, edit the file found in `php/configuration.php`. You need to edit the file actually used by the web server; this will usually be the one moved into the right place in the previous step.  
   Once the application is in place, and the DB credentials have been configured, you should initialize the DB itself; in order to do so, just point your browser at the following url: `http://<host>/<path>/php/setup/index.php`.  
   Here you will find the standard [POG][pog] setup page: it should be enough to click the "POG me up!" button at the bottom of the page, and then the "Process" button on the next page.  
   The POG interface will allow also a very basic access to the DB data that may be useful to check that the application is actually writing something on the DB (even if you will not be able to make much sense out of the data you will see, as they are all encrypted!)  
   More information about building the PHP backend may be found in the `doc/install.php.txt` file.
 
 
 ## Disclaimer
 
 This application has not been fully tested, so there may be still problems due to the new build script or to the new repository structure. So, for the moment, **use it at your own risk!**
