 Mining on the public Ethereum network is a complex task as it's only feasible using GPUs,
 requiring an OpenCL or CUDA enabled `ethminer` instance. For information on such a
 setup, please consult the [EtherMining subreddit](https://www.reddit.com/r/EtherMining/)

 In a private network setting, however a single CPU miner instance is more than enough for
 practical purposes as it can produce a stable stream of blocks at the correct intervals
