# Slint UEFI demo This example demonstrates Slint in a UEFI environment.  To build this example a suitable UEFI rust target must be installed first: ``` rustup target install x86_64-unknown-uefi ``` To build, simply pass the `--package` and `--target` arguments to cargo: ``` cargo build --package uefi-demo --target x86_64-unknown-uefi ``` The produced UEFI binary can then either be tested on real hardware by booting it like any other bootloader or directly with QEMU (the firmware location varies by distro): ``` qemu-system-x86_64 -bios /usr/share/edk2-ovmf/x64/OVMF.fd -kernel target/x86_64-unknown-uefi/debug/uefi-demo.efi ```
