It is pretty easy to install.  Just go here and download the latest image:

https://hiveos.farm/install

Then download and use HDD Raw Copy Tool to burn the image to USB or SSD from a windows computer.

Then you boot the rig from that image and it will ask you for a RidID and password, which you will be assigned when you create you first worker/rig after establishing an account by going here:

https://the.hiveos.farm/register/

Once that is done, you need to create a wallet, which is the BEAM address you want to mine to.

Next you create a flightsheet, where you specify the coin (BEAN), the wallet (the BEAM address you just created above), and the miner (GMiner).  When setting up the miner, you need to pick 150_5 for the algorithm, %WAL%.%WORKER_NAME% for the template, and there pool url, port and password, and you're done.
