# Pipeline - Explanations - Viewing booking system

The viewing booking system called Room Booker consists of a couple parts. In-depth explanations about how it works can be found on the [Room Booker GitHub page](https://github.com/BreakTools/RoomBooker). The backend runs on our Automation server. In the viewing room, above the door on top of the light panel, sits a small computer which is connected to the display outside the door. This computer runs Linux Mint in a virtualized environment through Proxmox, though Mint does have full access to the video card which allows it to output through HDMI. Proxmox can be accessed on [https://145.90.27.92:8006](https://145.90.27.92:8006). Reboot Linux Mint from there in case the display is not showing any output, as it seems that sometimes the display is not initialized properly when Linux Mint reboots itself.
