If you try a distro that does it by default then it is no more complicated then ext4 for the user. The distro will setup things for you. I know that opensuse Tumbleweed and Fedora Workstation set this up by default. Manually configuring is how ever a bit more complicated.
Albeit not completely beginner friendly, the arch wiki explains btrfs features and manual configuration pretty well. If you are looking for a guide to a snapshot tool, then it depends on your distro, but they probably have an article for it as well (also, check the "related articles" section at the top of the page).
Alternatively, I run OpenSUSE Tumbleweed on my main production rig and it uses BTRFS and sets up snapshots from the GRUB menu for you by default!
I'm also using Nvidia, so while it's gotten better and I haven't had to roll back in a long time, Snapper has saved my butt once or twice in the past. ;)
