1) Create a MySQL database and ASSIGN a MySQL User to it.
Go to phpMyAdmin and select the database then import the file located into "database/adfly.sql.zip" folder.

2) Step two is to open config.inc.php with a text editor and update your site url and mysql info
LINE 13 : $db = new ezSQL_mysql('DB_USER', 'DB_PASS', 'DB_NAME', 'localhost');

3) Admin URL is yoursite.com/admin.php
    ADMIN DETAILS CAN BE UPDATED INTO config.inc.php
    LINES 29 and 30
    define('ADMIN_USER', 'admin');
    define('ADMIN_PASS', md5('admin_pass'));

4) IMPORTANT! SETUP YOUR SITE URL. NO BACKSLASH REQUIRED.
LINE 27 : define('SITE', 'http://localhost:8888');

To add new languages rename "language/lang.your_language.php" to your language.
For example if you want to add german language :
Rename "lang.your_language.php" to "lang.de.php" then Edit lang.de.php like this :
$lang['your_language']['earn_money'] = 'Earn Money'; to $lang['de']['earn_money'] = 'Geld verdienen';
Last STEP : go into config.php line 38 and rename "require_once 'language/lang.your_language.php';" to "require_once 'language/lang.de.php';"
Changing default language : edit config.php line 45 from define('DEFAULT_LANGUAGE', 'en'); to "define('DEFAULT_LANGUAGE', 'de');"
