###################
-- `PHP <http://www.php.net/>`_ version 5.4 or newer is recommended and 5.2.4 as the absolute minimum required.
-- A Database is required for most web application programming.
+`PHP <http://www.php.net/>`_ version 5.4 or newer is recommended.

+It should work on 5.2.4 as well, but we strongly advise you NOT to run

- Currently supported databases are:
- MySQL (5.1+) via the *mysql* (deprecated), *mysqli* and *pdo* drivers
- Oracle via the *oci8* and *pdo* drivers
- PostgreSQL via the *postgre* and *pdo* drivers
