 # Laravel model validation rules
 
+[![Latest Version on Packagist](https://img.shields.io/packagist/v/korridor/laravel-model-validation-rules?style=flat-square)](https://packagist.org/packages/korridor/laravel-model-validation-rules)
+[![License](https://img.shields.io/packagist/l/korridor/laravel-model-validation-rules?style=flat-square)](license.md)
+[![TravisCI](https://img.shields.io/travis/korridor/laravel-model-validation-rules?style=flat-square)](https://travis-ci.org/korridor/laravel-model-validation-rules)
+[![StyleCI](https://styleci.io/repos/208495858/shield)](https://styleci.io/repos/208495858)
+
+This package is an alternative to the Laravel built-in validation rules `exists` and `unique`.
+It uses Eloquent models instead of directly querying the database.
+
+**Advantages**
+ - The rule can be easily extended with the Eloquent builder. (scopes etc.)
+ - Softdeletes are working out of the box.
+ - Logic implemented into the models work in the validation as well. (multi tenancy system, etc.)
+
 ## Installation
 
+You can install the package via composer with following command:
+
 ```bash
 composer require korridor/laravel-model-validation-rules
 ```
 
+### Translation
+
+If you want to customize the translations of the validation errors you can publish the translations 
+of the package to the `resources/lang/vendor/modelValidationRules` folder.
+
 ```bash
 php artisan vendor:publish --provider="Korridor\LaravelModelValidationRules\ModelValidationServiceProvider"
 ```
 
-## Usage

+
+ - 6.0
