Hi Ben. I am going to suggest you approach this differently. First, make sure you follow the setup instructions for Agency. Follow all those steps, and try to understand what they are doing. Then you will be able to ask pointed questions.
The way you asked for help here is considered weird, because Hugo as a project doesn’t provide the kind of support you are looking for. Being hesitant to use the software provides no leverage for you, but it comes off as condescending. So please set up the theme and site a few more times, following each of those steps until you understand what those steps do, and then you will have the questions you need to ask.
