 ## How to use  
 
-### On VM  
+### Download release  
 
-run ```./test.sh # only works on AMD64``` to run in VM using QEMU  
+#### On Real hardware  
 
-### On Real hardware  
+if your have amd64(x86_64) UEFI computer  
+Download release and copy the bootx64.efi to <USB_DRIVE>/EFI/BOOT/bootx64.efi case independent  
+
+#### On VM  
+
+run:  
+you will need OVMF firmware you can get it [here](https://qemu.weilnetz.de/test/ovmf/usr/share/OVMF/OVMF_CODE_4M.fd)
+```bash
+qemu-system-x86_64 -machine type=q35,accel=kvm -drive if=pflash,format=raw,readonly=on,file="$OVMF_CODE_PATH" -hda fat:rw:build -boot order=c -smp 4 -s -serial mon:stdio

 ## Controling  
 
-| Key | Action | Note |
-|-----|--------|------|
-| ARROW_UP | speed up | delays under 1ms may be unrelayable |
-| ARROW_DOWN | slow down | max delay is about UINT32_MAXμs |
-| PAGE_UP | speed up | 10x step |
-| PAGE_DOWN | speed down | 10x step |
-| Home key | reset speed | reset frame delay to 10ms |
-| Delete key | clear screen |  |
