 # Laravel-Unsplash
+[![StyleCI](https://styleci.io/repos/116019138/shield?branch=master)](https://styleci.io/repos/116019138)
 
+**This package contain pulic actions**
+
+## Install
+
+Via Composer
+
+``` bash
+$ composer require mahdimajidzadeh/laravel-unsplash
+```
+If you do not run Laravel 5.5 (or higher), then add the service provider in config/app.php:
+
+```
+MahdiMajidzadeh\LaravelUnsplash\LaravelUnsplashServiceProvider:class
+```
+
+If you do run the package on Laravel 5.5+, package auto-discovery takes care of the magic of adding the service provider.
+
+You must publish the configuration to provide an own service provider stub.
+
+``` bash
+$ php artisan vendor:publish --provider="MahdiMajidzadeh\LaravelUnsplash\LaravelUnsplashServiceProvider"
+```
+
+## Usage
+See documention for params and others at [unsplash docs](https://unsplash.com/documentation)
+
+List of methods: 
+
+### Photos
+
+``` php
+$unsplash  = new MahdiMajidzadeh\LaravelUnsplash\Photo();
+$photos    = $unsplash->photos($params)->get();          // list of all photos
+$photo     = $unsplash->single($id, $params)->get();     // single photo
+$statistic = $unsplash->statistic($id, $params)->get();  // single photo statistics
+$link      = $unsplash->download($id);                   // single photo download link
