Denied unemployment, how do I appeal? (update)

I was told my separation was for misconduct, which is not what happened. I am in Omaha, in case local advice matters. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
