Denied unemployment, how do I appeal? - 7 weeks in

My claim was denied after 7 weeks of waiting, and the letter says I have a short window to appeal. I do not usually post, so bear with me. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.
