WEBSITE REQUIREMENTS

List of web hosts confirmed to be working with Prometheus
- GameSwitchers - Kinda cheap, but has a limit of 2 databases on their cheapest webhosting
- NFOServers - Pretty cheap, but USA based
- GoDaddy - Since they use IIS it's highly likely the first time you install Prometheus it'll throw a 500 internal server error. Just contact their support if that happens.
If you have experience with Linux servers I'd suggest just getting a DigitalOcean droplet for $5 to run a webserver on. Though don't do this if you have no idea what you're doing.

How to check if your webserver supports Prometheus
Download the requirement checker and extract it on your webserver. Then visit the file called prometheus_check.php. It will now tell you if your PHP version can run Prometheus
