If you want to mine on a Windows Operating System, then you'll need to create a batch file to start your miner.
Simply open notepad and then copy and paste the following:
ethdcrminer64.exe -epool stratum.aikapool.com:9897 -ewal UserName.WorkerName -epsw YourWorkerPass -allpools 1
You then need to change "UserName.WorkerName" to reflect your own account. If you want, you can create additional workers with usernames and passwords of your choice here
4. Create a Ethereum-classic address to receive payments.
Generate a new address and input it on your account page to receive payments.
