 This guide is two fold, ease of use for mining on Linux distributions and some extra security around mining as most of these miners have not had security auditing.

 You have already done everything you need to do. You are now mining in a docker container with XMRig `ctrl+c` to exit the miner or add `-d` just after `docker run` to background the miner.
