The thing is, I don’t think a guide is really needed to install Linux. Most of it is pretty straight-forward. (The only tricky bit that comes to mind is making the USB that you’ve put your distro on bootable. That probably isn’t obvious; and it might not be obvious how to get your computer to boot from a USB anyway if you’ve never done it before.)
It's been awhile since I installed a Linux distro...Have some of them improved guidance related to allocating disk space on install? I remember that was one of the parts that I wasn't entirely confident I'd handled properly the last few times I did so. Something something swap, something /, and the like.
