1. Create account.
2. Download a miner.
3. Configure your miner.
If your using Linux, Then type the following into the console:
./sgminer -k groestlcoin -o stratum+tcp://grs.suprnova.cc:5544 -u Weblogin.WorkerName -p WorkerPassword
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:
sgminer -k groestlcoin -o stratum+tcp://grs.suprnova.cc:5544 -u Weblogin.WorkerName -p WorkerPassword
You then need to change "-u Weblogin.Worker -p Worker password" to reflect your own account. Eg, "-u Steve.StevesWorker -p StevesWorkerPassword" then go to "File > Save as" and save the file as "RunMe.bat" in the same folder containing your miners application files. You are now ready to mine, double click on "RunMe.bat" to start mining. If you want, you can create additional workers with usernames and passwords of your choice here
4. Create a Groestlcoin address to receive payments.
Generate a new address and input it on your account page to receive payments.
