## Usage

Add to your `.linthis/config.toml`:

```toml
[plugin]
sources = [
    {{ name = "{name}", url = "https://github.com/your-org/{name}.git" }},
]
```

### With Version Pinning

```toml
[plugin]
sources = [
    {{ name = "{name}", url = "https://github.com/your-org/{name}.git", ref = "v1.0.0" }},
]
```

## Customization

To override specific settings, you can:

1. **Layer plugins**: Add your overrides in a second plugin that loads after this one
2. **Local overrides**: Settings in your project's `.linthis/config.toml` override plugin settings
3. **Fork and modify**: Fork this repository and customize the configs

## Configuration Priority

Settings are applied in this order (later overrides earlier):

1. Built-in defaults
2. Plugin configs (in order listed in `sources`)
3. User config (`~/.linthis/config.toml`)
4. Project config (`.linthis/config.toml`)
5. CLI flags

## Contributing

1. Fork this repository
2. Make your changes
3. Test with: `linthis plugin validate .`
4. Submit a pull request
