General Process
Computer connects to a website using a browser in full screen mode, the website manages the content and redirects if needed. The PC should never need to be touched.
PC Config

NOTE : This is still in testing.
NOTE : Chromium is not in the repos for CentOS Stream. The computer I am using is very slow and I don't feel like compiling. Will use Chrome instead.[1]
- Minimal install of CentOS 9 Stream
- Dump of commands, could be used for a script. Change the URL to match your environment.
