+To use tweeper via web there are two options (the examples assume the
+installation directory to be `/usr/share/php/tweeper/`):
+
+1. Using the PHP built-in web server:
+
+  php -S localhost:8000 -t /usr/share/php/tweeper/
++
+and then visit 'http://localhost:8000/tweeper.php' in the web browser.

 
 

-Using tweeper via web (the symlink must be created only the very first time):
+2. Using a generic web server with the document root in '/var/www':

 
   sudo ln -s /usr/share/php/tweeper/tweeper.php /var/www
   xdg-open http://localhost/tweeper.php?src_url=http://twitter.com/NSAcareers
 
   sudo ln -s /usr/share/php/tweeper/tweeper.php /var/www
   xdg-open http://localhost/tweeper.php?src_url=http://twitter.com/NSAcareers

+It is enough to create the symlink only the very first time tweeper is used
+this way.
