Installation & setup
========================

You can install the package via composer:

```
composer require spatie/laravel-query-builder
```

The package will automatically register its service provider.

You can optionally publish the config file with:

```
php artisan vendor:publish --provider="Spatie\QueryBuilder\QueryBuilderServiceProvider" --tag="query-builder-config"
```

These are the contents of the default config file that will be published:

```

     * By default the package will use the `include`, `filter`, `sort`
     * and `fields` query parameters as described in the readme.
