-This will compile the targeted keyboard/keymap and leave the resulting `.hex` or `.bin` file in the QMK directory for you to flash. If `:keymap` is omitted, the `default` keymap is used. Note that the parameter format is the same as when building with `make`.

 You can also start the script without any parameters, in which case it will ask you to input the build parameters one by one, which you may find easier to use:

-If you're on Linux, this should work out of the box. On Windows and macOS, it requires [Docker Machine](http://gw.tnode.com/docker/docker-machine-with-usb-support-on-windows-macos/) to be running. This is tedious to set up, so it's not recommended; use QMK Toolbox instead.
