Getting Started with the Almika Pre-Filled System

Dear Cloud for Customer Community,

I just recently was granted access to the pre-filled C4C system (with the sample company Almika).  When I log in with my initial user, there's not much I can do.  According to the welcome e-mail, I'm supposed to unlock business users to start utilizing specific functionality (like sales).  I can unlock the user, but I can't figure out how to update the e-mail address of the user, so when I generate the password, it goes to a real e-mail address.

There must be some Getting Started document available.  Can someone please offer some initial help?

Thanks,

Tony
