# Zram
Because a Linux system requires swap to function properly install `zram-init`. To keep it simple, it will utilise RAM to store compressed swap.
Install it with:
```
# apk add zram-init
# rc-update add zram-init default
```
Now reboot the computer or restart the service to check if it works.
Also be sure to read the [ArchWiki](https://wiki.archlinux.org/title/Zram) for more information.
