That guide doesn't tell me how to use the miner. Like, I want to know what I need to do, to start mining with it.
If you look at the beginning of the guide, it will link to another article about setting up solo mining. While it is geared to GPU mining, you can use the same instructions to CPU mine. That is not a great idea because it will take years to find a block using yoru CPU.
Basically, start the commandline without a device listing. It will complain and list all your devices. You will see the device number for a CPU and any compatible GPUs.
