A new Linux user here looking for some tips – Info Linux

Hi there I just got Linux on my asus chromebook in not sure what Linux it is but here is the tutorial I used https://youtu.be/cIuUA3eY29s I’m new to Linux because well I usally use Windows but you can’t really get that on chromebook haha. I’m just looking for some tips and tricks that are good to know so far I’ve discovered the terminal is my best friend and I’ve already got Firefox and Minecraft on there. If y’all know of any tip tricks and even games for Linux let me know thanks- from a Linux newb
