+### Memory configuration
+
+Default Qubes allocates 4GB to dom0, and creates a 4GB SWAP partition. Since I have much better hardware, I opt to allocate 8GB to dom0 and use ZRAM instead.
+
+Increase dom0 memory by editing `/etc/default/grub` and changing dom0_mem=max:8192M.
+
+To use zram:
+- `qubes-dom0-update zram-generator`
+- Type the following file to `/etc/systemd/zram-generator`: https://raw.githubusercontent.com/TommyTran732/Linux-Setup-Scripts/main/etc/systemd/zram-generator.conf
+
+Reboot to apply the changes.
