I was very surprised how easy it was to set up the Bitaxe. I've had my Umbrel running for ages but thought adding a miner (it's only a toy really, no chance of actually mining any blocks) would be too complicated. Turns out all you have to do is plug it in and point it in the right direction. I then added the Public Pool app to my Umbrel and pointed it there instead of the default, and it works fine.
