This script is entirely automated. It will generate a downloadable wp-config.php file to use for your WordPress installation. At no point are your details stored, ANYWHERE. Once your config file is generated, all data you have entered is destroyed. Because of this, please ensure you enter all fields correctly, because if you submit the form and have made a mistake and need to correct it - you'll have to re-enter everything.
If you have any doubts about this script, the source code is available by going to here.
