From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sounds like you've gotten good answers about your formatting question. For the steam proton question, the answer is that yes, steam installs it automatically. You might have to mess with the proton version for specific games, so check https://www.protondb.com/ for your game if it doesn't work immediately.
Congrats on trying out Linux! I hope you enjoy it! I've never used Mint myself (I don't like ubuntu-type package management), nor the Cinnamon desktop (although I've heard good things), but that's part of the beauty of linux, there's so much to try! Mint is definitely a good starter distro, but if you find you enjoy messing around with it, you might consider a bit of distro-hopping.
