# Config

The `config` directory holds the theme's global configuration: the theme-wide settings you expose to sellers, and the values they've chosen.

```bash
└── theme
    ├── layout
    ├── sections
    ├── config
    │   ├── settings_schema.json
    │   └── settings_data.json
    ...
```

Both files are required.

| File | Purpose |
| ---- | ------- |
| [`settings_schema.json`](/themes/config/settings_schema) | Defines the theme settings and how they're grouped in the theme editor. |
| [`settings_data.json`](/themes/config/settings_data) | Stores the values chosen for those settings, plus data for [statically rendered](/themes/sections/overview#statically-render-a-section) sections. |

## How they fit together

`settings_schema.json` declares a setting once, for example a `font_family` select. The seller picks a value in the theme editor, and it's saved to `settings_data.json`. At render time the two are merged, with schema defaults filling any gap, and the result is exposed to Liquid as the global `settings` object.

```liquid
<body style="font-family: {{ settings.font_family }}">
```

Theme settings are read through `settings`, section settings through `section.settings`, and block settings through `block.settings`. See [Settings](/themes/settings/overview) for the setting types available in all three.
