Upgrading from 1.0.0
1.0.0 was based on Arch, so 1.0.1 is a fresh install. It wipes the disk you install it on. Back up first.

Requirements
- 2 GB RAM
- 64-bit or 32-bit x86 PC with UEFI or legacy BIOS, or an ARM64 machine with UEFI (turn Secure Boot off)
- 20 GB disk
Known issues
- Not yet tested on real hardware.
- The 32-bit build uses Debian 12 with Plasma 5, so its top bar is plain and has no clock.
- The live system keeps changes in memory only, so they are gone after a restart.
