## Start it

1. Write the ISO to a USB stick of 4 GB or more (balenaEtcher, Fedora Media Writer, Rufus in DD mode, or dd).
2. Start from the stick's UEFI entry. The live image is not signed yet: turn Secure Boot off, or use Setup Mode.
3. Choose Try WolOS (changes nothing) or Install WolOS (shows a summary before writing).

## Secure Boot key screen (first start after installing)

1. Press a key.
2. Choose Enroll MOK, then Continue, then Yes.
3. Password: `boot` (nothing shows while typing).
4. Choose Reboot. Missed it? Run `wol boot enroll` and restart.

## VirtualBox

Linux / Arch Linux (64-bit), EFI on, Secure Boot off for the live image, 6 GB and 4 CPUs (the test machine), VMSVGA with 128 MB or more, 32 GB disk, ISO on the optical drive. Known in 0.11.3: the installed desktop can stay black under VMSVGA; fixed in the 0.11.5 changelog entry.
