Simply open notepad and then copy and paste the following:
ethdcrminer64.exe -epool stratum.aikapool.com:9871 -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
