I am aware that having _software_ called FluxEngine and _hardware_ called
FluxEngine makes things complicated when you're not using the FluxEngine client
software with a FluxEngine board, but I'm afraid it's too late to change that
now. Sorry.
-If you're using Windows
------------------------

-In order to access the GreaseWeazle from Windows, you need to install a WinUSB
-driver for it. You can do this with the [Zadig](https://zadig.akeo.ie/)
-program. Download it, plug in the GreaseWeazle, and run it; select Options,
-List All Devices, and then open the big dropdown box and select the
-GreaseWeazle. You should see something like this.

-Ensure that the Driver boxes say `usbser` and `WinUSB`. Then press 'Replace
-Driver'. Once done, the GreaseWeazle will be visible to the FluxEngine client.

-**Important note!** Unfortunately, now, the original GreaseWeazle client won't
-work --- you can't use both drivers at once. I'm working on this. To switch
-back to the original driver, for using the GreaseWeazle client software
-instead, open up Zadig again, go through the same process, but make sure the
-left Driver box says `WinUSB` and the right one says `USB Serial (CDC)`. Now,
-when you press 'Replace Driver' the original driver will be restored.
+**If you were using a previous version on Windows** you might have installed
