How do I update the kemper rack?

So my Kemper arrived today, and apparently it isn't even up to date. I'm disappointed by that because my old Axe FX 2 XL+ arrived with the latest FW.

I downloaded the Rig Manager a few minutes ago and it told me the Kemper needs to be updtaed to 5.whatever.

I don't even know how to see what fw the kemper is on.
And the readme instructions and what i seen in the manual said we have to use a usb memory stick? I didn't think Kemper users had to do that anymore? I have usb from my PC plugged into the back of the kemper.

Anyway I plugged in a memory stick into the front of the kemper and nothing popped up saying to format it or transfer files or anything. so I don't know what i'm doing wrong.

I found a youtube video and finally figured out how to update. i was inserting the memory stick in the kemper thinking the kemper needed to format it first, then i found a how to video, and inserted it in my pc and coped the bin file and then when i inserted it in kemper it was recognised and did the update.
