What steps do I need to take?

I don't have a Battle.net account -- can I still play?
Absolutely! Just visit
Battle.net to create a free Battle.net account. Next, download the client from
https://us.battle.net/account/download/index.xml and install it. Create your BattleTag, and then log in to the game using your Battle.net account name (email address) and password to begin slaughtering the demonic hellspawn that dare stand in your way.
