 If your machine has a RAM size of 8GB or lower, I recommend that you create a separate partition for [ZRAM](https://wiki.archlinux.org/title/Zram), `/dev/sdaX`, as its backing device. `/dev/sdaY` will be a [Btrfs filesystem](https://wiki.archlinux.org/title/Btrfs) with the following subvolumes:

 ## Btrfs Snapshots
 
-Since we have set up our system to use Btrfs with a `@snapshots` subvolume, we will use [Snapper](https://snapper.io/) to create snapshots and [Btrfs Assistant](https://gitlab.com/btrfs-assistant/btrfs-assistant) as the frontend. [snap-pac](https://github.com/wesbarnett/snap-pac) is installed to create Btrfs snapshots before and after Pacman operations.

 ### Setting Up Snapper
 
-Start Btrfs Assistant and go to the *Snapper Settings* tab. Click *New* and name it `root` with backup path `/`. Enable *timeline snaphots*, adjust the snapshot retention times, and click *Save*. Click *New* again and name it `home` with backup path `/home`, enable *timeline snaphots*, adjust the snapshot retention times, and click *Save*. Lastly, enable *timeline*, *cleanup*, and *boot* in *systemd Unit Settings* section.
