 The data scraper can work "on the fly", that is, it can extract data from Allegro in real time when a request is made (from the point of view of your site, when a user visits some page). This ensures 100% data relevance and reduces the load on the server.
 Also, this Allegro crawler can be used to constantly scraping all the products, that is, saving and updating a full catalog of products. 
 
-## Use examples
+## Installation
+1) Install the scraper on your server. To do this, please contact: https://t.me/JWprogrammer
+2) Use the crawler in your project. Simply add the library to the project via the composer dependencies:
+```
+composer require jwprogrammer/allegro-scraper
+```
 
+## Use examples
+```
+$allegro = new \AllegroScraper\AllegroScraper();
+
+$result = $allegro->search([
+    'page' => 1,
+    'query' => 'Led halogen lampa',
+    'category' => 'czesci-samochodowe-620',
+    'order' => 'pd'
+]);
+if ($result->success) {
+    $result->totalCount;
+    foreach ($result->products as $product) {
+        $product->id;
+        $product->url;
+        $product->title;
