 3 | 
 4 | ![Screenshot](screenshot.png)
 5 | 
 6 | ## Features
 7 | - sends you notification emails when a game is available for a specific price or cheaper with informations about the seller (after sending that email the alert for this game is disabled and can be enabled again from the overview page)
 8 | - an overview website for adding and deleting games
 9 | 
10 | ## Requirements
11 | - PHP >= 5.4.0
12 | - a webserver that supports `.htaccess` files
13 | - a way to execute a script regularly (like cron or runwhen)
14 | 
15 | ## Setup
16 | 1. go to `setup.php` with your browser and copy the configuration generated into `config.php`
17 | 2. change the other options in in `config.php` according to your needs
18 | 3. create a cronjob or something similar to execute `notifications_check.php` regularly (e.g. every day)
19 | 3. Enjoy!
