@@ -4,6 +4,58 @@ Flutter package for Amazon PA-API 5.0.
 
 ## Getting Started
 
+As this package is not available via pub you have to add it manually to your `pubspec.yaml`. 
+There are at least two ways to use it in your project.
+
+### Option 1 - Add git repo to `pubspec.yaml`
+```yaml
+flutter_amazon_pa_api:
+  git:
+    url: https://github.com/meganii/flutter_amazon_pa_api.git
+    ref: master
+```
+
+### Option 2 - Add local copy to `pubspec.yaml`
+```yaml
+flutter_amazon_pa_api:
+  path: ../flutter_amazon_pa_api
+```   
+
+## Usage in your project
+After adding the package to your `pubspec.yaml` you have to add the package to your code.
+```dart
+import 'package:flutter_amazon_pa_api/flutter_amazon_pa_api.dart';
+import 'package:flutter_amazon_pa_api/search_items_response.dart';
+import 'package:flutter_amazon_pa_api/paapi_resource.dart';
+
+// list all resources you want to fetch
+var resources = [
+      PaAPIResource.BrowseNodeInfo_BrowseNodes.name,
+      PaAPIResource.Images_Primary_Small.name,

+      PaAPIResource.ItemInfo_ContentInfo.name,
+      PaAPIResource.ItemInfo_Title.name,
+      PaAPIResource.Offers_Listings_Price.name,
+      PaAPIResource.Offers_Listings_SavingBasis.name,
+      PaAPIResource.Offers_Listings_Availability_MaxOrderQuantity.name,
+      PaAPIResource.Offers_Listings_DeliveryInfo_IsAmazonFulfilled.name,
+    ];
+
+PaAPI paAPI = PaAPI(
+      accessKey: "<your access key>",
+      secretKey: "<your secretkey>",
+      partnerTag: "<your partner tag>",
+      // marketplace is defaulting to US. Use the PaAPIMarketplace enum to select your marketplace
+      marketplace: PaAPIMarketplace.de);
+
+// this will get all Items for this ASIN
+await paAPI.getItems(["B00S7N8G2Q"], resources);
+// this will get all Items for these keywords
+await paAPI.searchItems("urban classics damen ladies laces dress kleid", resources)
