1. The `project_slug` is used as a directory name for your Python project where spaces and underscores are replaced-with-dashes. It's also used for a few example variables where `we_use_underscores` instead.
2. The `use_rich_logging` variable adds settings and examples that make ample use of the [Rich package](https://github.com/Textualize/rich/) for beautiful logging. You typically want this so it defaults to `yes`. Just hit `Enter` to confirm. The setting also adds necessary requirements.
3. With `use_config_ini` you're getting a boat load of functions, presets, variables and examples that integrate a config.ini file via the `configparser` module.
4. Lastly with `use_inflect` you're adding the `inflect` module which does grammatically correct text rendering such as plural and singular. It also includes a few examples.
