# otter-config-types

> Typed config structs shared across Otter Shell apps and otter-settings.

`otter-config-types` is the Zig structs `otter-conf` parses for each app. `otter-settings` edits the same types at runtime.

New configurable app? Add the struct here first, then a tab in `otter-settings/src/tabs.zig`.

## Quick example

```zig theme={null}
const config_types = @import("otter_config_types");
const BarConfig = config_types.bar.Config;
```
