Setting up worker on Nice Hash

[theashp]

Hi Guys, hope someone can help. Im new to this s not super techy.

I have an Antminer D3 coming and im trying to setup mining pools so i'm ready. One of these is NICEHASH.

I understand how to generate what i need for the first field (the stratum) assuming of course i simply paste in what i'm given at Nicehash when i stipulate X11 and Europe, but i don't understand how to configure the worker. Can anyone explain in simple terms how i generate the worker and password. I read somewhere else it could be your user name and password but that doesn't seem right. I don't see anyway to CREATE WORKER in Nicehash

Thanks very much.

Also looking for other mining pool recommends.

Thanks,
