Building on Linux:

These instructions are for Debian-based distros and were tested with Debian 10 and Ubuntu 18.04. For others it should be similar.

Note: this is experimental. You're pretty much on your own if you encounter any problems with running the application.

• Install Mono. The mono-complete package from the Debian repo doesn't include msbuild, so you have to install mono-complete by following the instructions on the Mono project's website: https://www.mono-project.com/download/stable/#download-lin
• Install additional required packages: sudo apt install make g++ git libx11-dev mesa-common-dev
• Go to a directory of your choice and clone the repository (it'll automatically create a high-voltage-ring directory in the current directory): git clone https://git.do.srb2.org/KartKrew/high-voltage-ring.git
• Compile HVR: cd high-voltage-ring && make
• Run HVR: cd Build && ./builder
