So the wiki is a little out of date with regards to Spiral knights on Linux. I figured I'd post my guide on how to install and run the game on ANY distribution (I have tested this method out on Debian, Ubuntu, Pop!_OS, Fedora, Linux Mint, Solus OS, and OpenSUSE Tumbleweed). This guide also does not require invoking "sudo" or any sort of administrative commands or actions.

So that future Linux users have do not have to go hunting around as much, please sticky this video tutorial, or update the wiki accordingly to show a similar method used in my video.

With that said, happy dungeon crawling folks! =)
