Denied unemployment, how do I appeal? - first time posting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a line cook. I am in Baltimore, in case local advice matters. My employer's version of events does not match mine, and I have emails that show it.

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

Thanks for writing this out. I went through something close to it 6 months ago, and it got easier once I kept a simple log of every call and form.
