Documentation or Quickstart

I'm trying to use Ext4Fs to partition SD cards and install software for a Linux embedded system.
I want to partition an SD card in to 4 partitions, format each partition (MSDOS, ext4, ext4, ext4) and then write files onto each of the partitions. Currently I do this via a Linux system on an embedded device but would like to do it from native Windows PC if possible.

I've installed the driver, but can't get Windows to recognize my Linux formatted SD cards when I insert them.

How do I use Ext4Fsd?

Are there any documents or quickstart info?
I note the original website seems to be down (no domain?)

How can I tell if the driver is loaded and running ok?
How can I tell if the driver signing is enabled is disabled?

Thanks,
Brendan.
