Why do this? Why can't I just create my own things? Why bring everything from the example up?
I don't mind this, just trying to understand the logic.
Each theme has it's own specific settings. The example gives you all of those settings without having to read through all of their theme and find the settings for yourself. You can delete the files in content/ that you don't need. It's just a way to show you how to use the theme and give you a default config.toml.
