+# Image Comparator Laravel: Compare images using Laravel
+
+This package is a wrapper of [Image Comparator package](https://github.com/sapientpro/image-comparator)
+adapted to use with Laravel via Facade. All methods of Image Comparator are available in the Facade.
+For the method reference visit the [wiki](https://github.com/sapientpro/image-comparator/wiki)
+
+## Prerequisites
+* php 8.1 or higher
+* Laravel 8 or higher
+* Gd extension enabled
+
+## Installation
+
+You can install the package using Composer:
+`composer require sapientpro/image-comparator-laravel`
+
+## Usage
+
+You can start using the Image Comparator Facade by including it in your class:
+
+```php
+use SapientPro\ImageComparatorLaravel\Facades\Comparator;
+
+$imageHash = Comparator::hashImage('path_to_image.jpg')
+```
+
+By default, the average hashing algorithm is user for hashing and comparing images.
+If you want to use difference hashing algorithm, you set it with `setHashStrategy()` function:
+
+```php
+use SapientPro\ImageComparatorLaravel\Facades\Comparator;
+use SapientPro\ImageComparator\Strategy\DifferenceHashStrategy;
+
+Comparator::setHashStrategy(new DifferenceHashStrategy());
+
+$similarity = Comparator::compare('path_to_image1.jpg', 'path_to_image2.jpg') // will use difference hash algorithm
+```
+
