Got a denial letter for unemployment, what now? (Fresno)

I was told my separation was for misconduct, which is not what happened. I do not usually post, so bear with me. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
